Open Science Grid (OSG) Ticket Synchronization: Keeping Your Home Field Advantage In A Distributed Environment  

NASA Astrophysics Data System (ADS)

Large distributed computing collaborations, such as the Worldwide LHC Computing Grid (WLCG), face many issues when it comes to providing a working grid environment for their users. One of these is exchanging tickets between various ticketing systems in use by grid collaborations. Ticket systems such as Footprints, RT, Remedy, and ServiceNow all have different schema that must be addressed in order to provide a reliable exchange of information between support entities and users in different grid environments. To combat this problem, OSG Operations has created a ticket synchronization interface called GOC-TX that relies on web services instead of error-prone email parsing methods of the past. Synchronizing tickets between different ticketing systems allows any user or support entity to work on a ticket in their home environment, thus providing a familiar and comfortable place to provide updates without having to learn another ticketing system. The interface is built in a way that it is generic enough that it can be customized for nearly any ticketing system with a web-service interface with only minor changes. This allows us to be flexible and rapidly bring new ticket synchronization online. Synchronization can be triggered by different methods including mail, web services interface, and active messaging. GOC-TX currently interfaces with Global Grid User Support (GGUS) for WLCG, Remedy at Brookhaven National Lab (BNL), and Request Tracker (RT) at the Virtual Data Toolkit (VDT). Work is progressing on the Fermi National Accelerator Laboratory (FNAL) ServiceNow synchronization. This paper will explain the problems faced by OSG and how they led OSG to create and implement this ticket synchronization system along with the technical details that allow synchronization to be preformed at a production level.

Definition and implementation of a SAML-XACML profile for authorization interoperability across Grid middleware implementations in OSG and EGEE.  

SciTech Connect

In order to ensure interoperability between middleware and authorization infrastructures used in the Open Science Grid (OSG) and the Enabling Grids for E-science (EGEE) projects, an Authorization Interoperability activity was initiated in 2006. The interoperability goal was met in two phases: firstly, agreeing on a common authorization query interface and protocol with an associated profile that ensures standardized use of attributes and obligations; and secondly implementing, testing, and deploying on OSG and EGEE, middleware that supports the interoperability protocol and profile. The activity has involved people from OSG, EGEE, the Globus Toolkit project, and the Condor project. This paper presents a summary of the agreed-upon protocol, profile and the software components involved.

A dynamic system for ATLAS software installation on OSG grid sites  

NASA Astrophysics Data System (ADS)

A dynamic and reliable system for installing the ATLAS software releases on Grid sites is crucial to guarantee the timely and smooth start of ATLAS production and reduce its failure rate. In this paper, we discuss the issues encountered in the previous software installation system, and introduce the new approach, which is built upon the new development in the areas of the ATLAS workload management system (PanDA), and software package management system (pacman). It is also designed to integrate with the EGEE ATLAS software installation framework. In the new system, ATLAS software releases are packaged as pacball, a uniquely identifiable and reproducible self-installing data file. The distribution of pacballs to remote sites is managed by ATLAS data management system (DQ2) and PanDA server. The installation on remote sites is automatically triggered by the PanDA pilot jobs. The installation job payload connects to a central ATLAS software installation portal, making the information of installation status easily accessible across OSG and EGEE Grids. The issues encountered in running the new system in production, and our future plan for improvement, will also be discussed.

SVOPME: A scalable virtual organization privileges management environment  

SciTech Connect

Grids enable uniform access to resources by implementing standard interfaces to resource gateways. In the Open Science Grid (OSG), privileges are granted on the basis of the user's membership to a Virtual Organization (VO). However, Grid sites are solely responsible to determine and control access privileges to resources using users identity and personal attributes, which are available through Grid credentials. While this guarantees full control on access rights to the sites, it makes VO privileges heterogeneous throughout the Grid and hardly fits with the Grid paradigm of uniform access to resources. To address these challenges, we are developing the Scalable Virtual Organization Privileges Management Environment (SVOPME), which provides tools for VOs to define and publish desired privileges and assists sites to provide the appropriate access policies. Moreover, SVOPME provides tools for Grid sites to analyze site access policies for various resources, verify compliance with preferred VO policies, and generate directives for site administrators on how the local access policies can be amended to achieve such compliance without taking control of local configurations away from site administrators. This paper discusses what access policies are of interest to the OSG community and how SVOPME implements privilege management for OSG.

XACML profile and implementation for authorization interoperability between OSG and EGEE  

SciTech Connect

The Open Science Grid (OSG) and the Enabling Grids for E-sciencE (EGEE) have a common security model, based on Public Key Infrastructure. Grid resources grant access to users because of their membership in a Virtual Organization (VO), rather than on personal identity. Users push VO membership information to resources in the form of identity attributes, thus declaring that resources will be consumed on behalf of a specific group inside the organizational structure of the VO. Resources contact an access policies repository, centralized at each site, to grant the appropriate privileges for that VO group. Before the work in this paper, despite the commonality of the model, OSG and EGEE used different protocols for the communication between resources and the policy repositories. Hence, middleware developed for one Grid could not naturally be deployed on the other Grid, since the authorization module of the middleware would have to be enhanced to support the other Grid's communication protocol. In addition, maintenance and support for different authorization call-out protocols represents a duplication of effort for our relatively small community. To address these issues, OSG and EGEE initiated a joint project on authorization interoperability. The project defined a common communication protocol and attribute identity profile for authorization call-out and provided implementation and integration with major Grid middleware. The activity had resonance with middleware development communities, such as the Globus Toolkit and Condor, who decided to join the collaboration and contribute requirements and software. In this paper, we discuss the main elements of the profile, its implementation, and deployment in EGEE and OSG. We focus in particular on the operations of the authorization infrastructures of both Grids.

Supporting Shared Resource Usage for a Diverse User Community: the OSG Experience and Lessons Learned  

NASA Astrophysics Data System (ADS)

The Open Science Grid (OSG) supports a diverse community of new and existing users in adopting and making effective use of the Distributed High Throughput Computing (DHTC) model. The LHC user community has deep local support within the experiments. For other smaller communities and individual users the OSG provides consulting and technical services through the User Support area. We describe these sometimes successful and sometimes not so successful experiences and analyze lessons learned that are helping us improve our services. The services offered include forums to enable shared learning and mutual support, tutorials and documentation for new technology, and troubleshooting of problematic or systemic failure modes. For new communities and users, we bootstrap their use of the distributed high throughput computing technologies and resources available on the OSG by following a phased approach. We first adapt the application and run a small production campaign on a subset of “friendly” sites. Only then do we move the user to run full production campaigns across the many remote sites on the OSG, adding to the community resources up to hundreds of thousands of CPU hours per day. This scaling up generates new challenges - like no determinism in the time to job completion, and diverse errors due to the heterogeneity of the configurations and environments - so some attention is needed to get good results. We cover recent experiences with image simulation for the Large Synoptic Survey Telescope (LSST), small-file large volume data movement for the Dark Energy Survey (DES), civil engineering simulation with the Network for Earthquake Engineering Simulation (NEES), and accelerator modeling with the Electron Ion Collider group at BNL. We will categorize and analyze the use cases and describe how our processes are evolving based on lessons learned.

DZero data-intensive computing on the Open Science Grid  

SciTech Connect

High energy physics experiments periodically reprocess data, in order to take advantage of improved understanding of the detector and the data processing code. Between February and May 2007, the DZero experiment has reprocessed a substantial fraction of its dataset. This consists of half a billion events, corresponding to about 100 TB of data, organized in 300,000 files. The activity utilized resources from sites around the world, including a dozen sites participating to the Open Science Grid consortium (OSG). About 1,500 jobs were run every day across the OSG, consuming and producing hundreds of Gigabytes of data. Access to OSG computing and storage resources was coordinated by the SAM-Grid system. This system organized job access to a complex topology of data queues and job scheduling to clusters, using a SAM-Grid to OSG job forwarding infrastructure. For the first time in the lifetime of the experiment, a data intensive production activity was managed on a general purpose grid, such as OSG. This paper describes the implications of using OSG, where all resources are granted following an opportunistic model, the challenges of operating a data intensive activity over such large computing infrastructure, and the lessons learned throughout the project.

The event notification and alarm system for the Open Science Grid operations center  

NASA Astrophysics Data System (ADS)

The Open Science Grid Operations (OSG) Team operates a distributed set of services and tools that enable the utilization of the OSG by several HEP projects. Without these services users of the OSG would not be able to run jobs, locate resources, obtain information about the status of systems or generally use the OSG. For this reason these services must be highly available. This paper describes the automated monitoring and notification systems used to diagnose and report problems. Described here are the means used by OSG Operations to monitor systems such as physical facilities, network operations, server health, service availability and software error events. Once detected, an error condition generates a message sent to, for example, Email, SMS, Twitter, an Instant Message Server, etc. The mechanism being developed to integrate these monitoring systems into a prioritized and configurable alarming system is emphasized.

Guanine Nucleotide Exchange Factor OSG-1 Confers Functional Aging via Dysregulated Rho Signaling in Caenorhabditis elegans Neurons.  

PubMed

Rho signaling regulates a variety of biological processes, but whether it is implicated in aging remains an open question. Here we show that a guanine nucleotide exchange factor of the Dbl family, OSG-1, confers functional aging by dysregulating Rho GTPases activities in C. elegans. Thus, gene reporter analysis revealed widespread OSG-1 expression in muscle and neurons. Loss of OSG-1 gene function was not associated with developmental defects. In contrast, suppression of OSG-1 lessened loss of function (chemotaxis) in ASE sensory neurons subjected to conditions of oxidative stress generated during natural aging, by oxidative challenges, or by genetic mutations. RNAi analysis showed that OSG-1 was specific toward activation of RHO-1 GTPase signaling. RNAi further implicated actin-binding proteins ARX-3 and ARX-5, thus the actin cytoskeleton, as one of the targets of OSG-1/RHO-1 signaling. Taken together these data suggest that OSG-1 is recruited under conditions of oxidative stress, a hallmark of aging, and contributes to promote loss of neuronal function by affecting the actin cytoskeleton via altered RHO-1 activity.

Gratia: New Challenges in Grid Accounting  

NASA Astrophysics Data System (ADS)

Gratia originated as an accounting system for batch systems and Linux process accounting. In production since 2006 at FNAL, it was adopted by the Open Science Grid as a distributed, grid-wide accounting system in 2007. Since adoption Gratia's next challenge has been to adapt to an explosive increase in data volume and to handle several new categories of accounting data. Gratia now accounts for regular grid jobs, file transfers, glide-in jobs, and the state of grid services. We show that Gratia gives access to a thorough picture of the OSG and discuss the complexity caused by newer grid techniques such as pilot jobs, job forwarding, and backfill.

ReSS: Resource Selection Service for National and Campus Grid Infrastructure  

SciTech Connect

The Open Science Grid (OSG) offers access to around hundred Compute elements (CE) and storage elements (SE) via standard Grid interfaces. The Resource Selection Service (ReSS) is a push-based workload management system that is integrated with the OSG information systems and resources. ReSS integrates standard Grid tools such as Condor, as a brokering service and the gLite CEMon, for gathering and publishing resource information in GLUE Schema format. ReSS is used in OSG by Virtual Organizations (VO) such as Dark Energy Survey (DES), DZero and Engagement VO. ReSS is also used as a Resource Selection Service for Campus Grids, such as FermiGrid. VOs use ReSS to automate the resource selection in their workload management system to run jobs over the grid. In the past year, the system has been enhanced to enable publication and selection of storage resources and of any special software or software libraries (like MPI libraries) installed at computing resources. In this paper, we discuss the Resource Selection Service, its typical usage on the two scales of a National Cyber Infrastructure Grid, such as OSG, and of a campus Grid, such as FermiGrid.

Public storage for the Open Science Grid  

NASA Astrophysics Data System (ADS)

The Open Science Grid infrastructure doesn't provide efficient means to manage public storage offered by participating sites. A Virtual Organization that relies on opportunistic storage has difficulties finding appropriate storage, verifying its availability, and monitoring its utilization. The involvement of the production manager, site administrators and VO support personnel is required to allocate or rescind storage space. One of the main requirements for Public Storage implementation is that it should use SRM or GridFTP protocols to access the Storage Elements provided by the OSG Sites and not put any additional burden on sites. By policy, no new services related to Public Storage can be installed and run on OSG sites. Opportunistic users also have difficulties in accessing the OSG Storage Elements during the execution of jobs. A typical users' data management workflow includes pre-staging common data on sites before a job's execution, then storing for a subsequent download to a local institution the output data produced by a job on a worker node. When the amount of data is significant, the only means to temporarily store the data is to upload it to one of the Storage Elements. In order to do that, a user's job should be aware of the storage location, availability, and free space. After a successful data upload, users must somehow keep track of the data's location for future access. In this presentation we propose solutions for storage management and data handling issues in the OSG. We are investigating the feasibility of using the integrated Rule-Oriented Data System developed at RENCI as a front-end service to the OSG SEs. The current architecture, state of deployment and performance test results will be discussed. We will also provide examples of current usage of the system by beta-users.

Testisimmune privilege - Assumptions versus facts  

PubMed Central

The testis has long enjoyed a reputation as an immunologically privileged site based on its ability to protect auto-antigenic germ cells and provide an optimal environment for the extended survival of transplanted allo- or xeno-grafts. Exploration of the role of anatomical, physiological, immunological and cellular components in testis immune privilege revealed that the tolerogenic environment of the testis is a result of the immunomodulatory factors expressed or secreted by testicular cells (mainly Sertoli cells, peritubular myoid cells, Leydig cells, and resident macrophages). The blood-testis barrier/Sertoli cell barrier, is also important to seclude advanced germ cells but its requirement in testis immune privilege needs further investigation. Testicular immune privilege is not permanent, as an effective immune response can be mounted against transplanted tissue, and bacterial/viral infections in the testis can be effectively eliminated. Overall, the cellular components control the fate of the immune response and can shift the response from immunodestructive to immunoprotective, resulting in immune privilege. PMID:25309630

Analysis of the Current Use, Benefit, and Value of the Open Science Grid  

SciTech Connect

The Open Science Grid usage has ramped up more than 25% in the past twelve months due to both the increase in throughput of the core stakeholders - US LHC, LIGO and Run II - and increase in usage by nonphysics communities. It is important to understand the value collaborative projects, such as the OSG, contribute to the scientific community. This needs to be cognizant of the environment of commercial cloud offerings, the evolving and maturing middleware for grid based distributed computing, and the evolution in science and research dependence on computation. We present a first categorization of OSG value and analysis across several different aspects of the Consortium's goals and activities. And lastly, we presents some of the upcoming challenges of LHC data analysis ramp up and our ongoing contributions to the World Wide LHC Computing Grid.

Does innate immune privilege exist?  

PubMed

Immune privilege in the eye is believed to originate from the eye's need to avoid the sight-destroying consequences of inflammation. Over the past 25 years, many of the anatomical, cellular, and molecular mechanisms by which the eye avoids inflammation secondary to adaptive immune responses have been elucidated. In the recent past, it has become increasingly clear that innate immune responses play a critical role in activating the adaptive immune response. Moreover, innate immunity itself carries a heavy burden of inflammation, thereby posing a threat to vision if it should occur intraocularly. Ocular immunologists have now begun to inquire into the extent to which the eye regulates the expression of innate immunity in oculi. Evidence is presented which indicates that factors found in normal aqueous humor (1) prevent NK cells from lysing their targets, (2) inhibit neutrophil activation by CD95 ligand, (3) suppress nitric oxide production by activated macrophages, and (4) interfere with complement activation via the alternative pathway. These factors include transforming growth factor-beta2, alpha-melanocyte-stimulating hormone, calcitonin gene-related peptide, and migration inhibitory factor. The ability of the eye to prevent intraocular activation of innate immune effectors spares the corneal endothelium (which expresses CD95 ligand constitutively, but low levels of MHC class I molecules) from destruction by NK cells and neutrophils, and protects the visual axis from distortion by macrophage and complement-mediated inflammation. Thus, privilege exists in the eye for both adaptive and innate immunity. PMID:10770279

Open Science Grid: Linking Universities and Laboratories In National Cyberinfrastructure  

NASA Astrophysics Data System (ADS)

Open Science Grid is a consortium of researchers from universities and national laboratories that operates a national computing infrastructure serving large-scale scientific and engineering research. While OSG's scale has been primarily driven by the demands of the LHC experiments, it currently serves particle and nuclear physics, gravitational wave searches, digital astronomy, genomic science, weather forecasting, molecular modeling, structural biology and nanoscience. The OSG distributed computing facility links campus and regional computing resources and is a major component of the Worldwide LHC Computing Grid (WLCG) that handles the massive computing and storage needs of experiments at the Large Hadron Collider. This collaborative work has provided a wealth of results, including powerful new software tools and services; a uniform packaging scheme (the Virtual Data Toolkit) that simplifies software deployment across many sites in the US and Europe; integration of complex tools and services in large science applications; multiple education and outreach projects; and new approaches to integrating advanced network infrastructure in scientific computing applications. More importantly, OSG has provided unique collaborative opportunities between researchers in a variety of research disciplines.

Challenging privilege through Africentric social work practice.  

PubMed

Privilege refers to the unearned advantages enjoyed by a particular group simply because of membership in that group. Privileges accrue to those who (consciously or not) oppress others and are generally invisible to those who enjoy them. In seeing reality from the standpoint of other groups, one acquires the vantage point necessary to see privilege and its effects. Africentric theory describes the ethos and values of Africans and African Americans and provides a standpoint from which social workers can more effectively identify and build on the strengths of African Americans. Building on the concept "loss of terms," Africentric theory provides a framework within which social workers can challenge the invisible hegemony of privilege. This article challenges social workers to understand the nature of privilege as it relates to oppression and to develop a profound multicultural literacy that is carefully translated into practice imperatives.

FermiGrid - experience and future plans  

SciTech Connect

Fermilab supports a scientific program that includes experiments and scientists located across the globe. In order to better serve this community, Fermilab has placed its production computer resources in a Campus Grid infrastructure called 'FermiGrid'. The FermiGrid infrastructure allows the large experiments at Fermilab to have priority access to their own resources, enables sharing of these resources in an opportunistic fashion, and movement of work (jobs, data) between the Campus Grid and National Grids such as Open Science Grid and the WLCG. FermiGrid resources support multiple Virtual Organizations (VOs), including VOs from the Open Science Grid (OSG), EGEE and the Worldwide LHC Computing Grid Collaboration (WLCG). Fermilab also makes leading contributions to the Open Science Grid in the areas of accounting, batch computing, grid security, job management, resource selection, site infrastructure, storage management, and VO services. Through the FermiGrid interfaces, authenticated and authorized VOs and individuals may access our core grid services, the 10,000+ Fermilab resident CPUs, near-petabyte (including CMS) online disk pools and the multi-petabyte Fermilab Mass Storage System. These core grid services include a site wide Globus gatekeeper, VO management services for several VOs, Fermilab site authorization services, grid user mapping services, as well as job accounting and monitoring, resource selection and data movement services. Access to these services is via standard and well-supported grid interfaces. We will report on the user experience of using the FermiGrid campus infrastructure interfaced to a national cyberinfrastructure--the successes and the problems.

Genetically engineered immune privileged Sertoli cells  

PubMed Central

Sertoli cells are immune privileged cells, important for controlling the immune response to male germ cells as well as maintaining the tolerogenic environment in the testis. Additionally, ectopic Sertoli cells have been shown to survive and protect co-grafted cells when transplanted across immunological barriers. The survival of ectopic Sertoli cells has led to the idea that they could be used in cell based gene therapy. In this review, we provide a brief overview of testis immune privilege and Sertoli cell transplantation, factors contributing to Sertoli cell immune privilege, the challenges faced by viral vector gene therapy, the use of immune privileged cells in cell based gene therapy and describe several recent studies on the use of genetically engineered Sertoli cells to provide continuous delivery of therapeutic proteins.

Pedagogy of the Privileged: Review of Deconstructing Privilege: Teaching and Learning as Allies in the Classroom.  

PubMed

As scholarship and research in multicultural psychology evolves to a multilayered and complex discipline, increased attention to the role of larger structural forces of privilege has come to the forefront. Intersectionality of sociopolitical identities and the role those with privilege have in confronting oppression becomes a critical component of multicultural education. The edited volume, Deconstructing Privilege: Teaching and Learning as Allies in the Classroom (Case, 2013) provides concrete guidance and examples for educators seeking to enhance their approach to teaching privilege as a necessary mirror of oppression. This review highlights strengths of the book for educators in psychology and suggests recommendations for more complex discussion of the integration of privilege within the framework of structural oppression.

Review of ocular immune privilege in the year 2010: modifying the immune privilege of the eye.  

PubMed

The original evidence for the existence of immunologically privileged sites in the body was based on the prolonged survival of genetically disparate transplanted tissue in the anterior chamber of the eye. The failure of the immune system to elicit an immune response in this and other such sites constitutes the hallmark of the immune privilege status. The remarkably successful field of corneal transplantation in clinical practice is undoubtedly associated with corneal immune privilege. Several investigations have addressed the regulatory mechanisms governing this phenomenon, which involves a complex interplay between multiple molecular and cellular pathways. Furthermore, the use of various transgenic mouse models has facilitated the identification of critical pathways, which upon disruption can modify the immune privileged status of the eye. Understanding these pathways not only reveals the mechanisms underlying various ocular inflammatory disease conditions, but also has clinical implications for the transplantation field and for the treatment of autoimmunity.

Thank you for the privilege  

PubMed Central

Thank you for the privilege to serve as the EFOST President. I am deeply humbled for having been selected to serve as the new President of EFOST: this is not for the work that I have undertaken, but for what others around me have done. I hope that my past duties as President of BOSTAA, and as president of the Sports and Exercise Medicine of the Royal Society of Medicine will help me in performing these my new duties. It all started in 1992, and the EFOST is now just leaving its adolescent phase, with all its teenager problems. There is truth in Newton’s quote about standing on the shoulders of giants. Francois, you and the other leaders at EFOST have generated the momentum to keep moving EFOST forward, and the wisdom to keep it moving in the right direction. We all benefited from your contributions, dedication and volunteerism. To step into this role feels a little like steering a train. EFOST operates under a strategic plan which sets our direction and controls how the changing succession of leaders navigates. This plan is critical to helping us maintain focus, direction, and purpose. It is crucial that we focus on our strategic direction. However, we must continue to monitor the environment around us. We must recognize the changing influences so that we can respond appropriately. Europe is in a state of flux, with great challenges, both scientifically and economically. Strategically, we recognized all this a while ago, and we have tried, and succeeded, to be inclusive. The policy has worked, and we have embraced, and we have been embraced, by several countries during Dr Kelberine’s tenure. I can only thank him and the Board for this vision, and can confirm that I wish this train to continue to move in this direction. A train can only move if it is on the right tracks: I look forward to work with the great engineers of the organization, and welcome the help of the Board of Trustees to keep us on track. EFOST was born as a get together of a group of friends, and is the baby that was born from the ideas and ideals of several individuals who are in this room today. To them, my thanks for such ideas and ideals, and an assurance: I wish to uphold them. EFOST will need to move forward, and to ensure that the needs of the Sports Trauma Societies which form, sustain, foster and nurture it are satisfied. For this, one of the charges given to me was to change the bylaws. The process was thorny, but the results have been here for all to see: a flexible, dynamic Executive Board, and a Board at Large which is really representative of all Europe. From you, I expect support. To you, I offer dedication. The life of a President is often lonely. I am a social animal, and I do not wish to be lonely. I intend to use the help and advice of my Past President, Francois, and to have the support of my Vice President, Gernot. I take this opportunity to thank them in advance, and to apologise to them in advance: I know that it is difficult to work with me. I want things yesterday, and, despite 28 years outside of Italy, my Italian quick fire temper can still surface. EFOST is a great organization, and it has forged great links. You have all seen how the work that Burt has undertaken and the endless meetings that Francois has held have borne fruits: the EFOST-AOSSM traveling fellowship is now a reality, and the support given by all of you on the Board has been superb: many thanks. One of our Past Presidents, Paco Biosca, is now the Chief Medical Officer of Chelsea: with him, we have succeeded in establishing a football Team Physician fellowship, and we look forward to strengthening these ties. More on fellowships during the years of my tenure. But remember: it will not be my doing, it will be the work of all of you, of all of us. EFOST will need to speak with one voice to the world and the sister organizations. In Europe, we have all too often projected the wrong image of weak leadership and of having more than one train controller. The work that Francois has undertaken has ensured that everybody on the Executive Board sang from the

White Privilege and Male Privilege: A Personal Account of Coming To See Correspondences through Work in Women's Studies. Working Paper No. 189.

In much the same way that men are not taught to acknowledge all the ways they are privileged in society, whites are not taught to recognize how their status as white people confers on them many privileges. Arguing that male privilege and white privilege are interrelated, and that both types of privilege are unearned and unjustified, this paper…

OASIS: a data and software distribution service for Open Science Grid  

NASA Astrophysics Data System (ADS)

The Open Science Grid encourages the concept of software portability: a user's scientific application should be able to run at as many sites as possible. It is necessary to provide a mechanism for OSG Virtual Organizations to install software at sites. Since its initial release, the OSG Compute Element has provided an application software installation directory to Virtual Organizations, where they can create their own sub-directory, install software into that sub-directory, and have the directory shared on the worker nodes at that site. The current model has shortcomings with regard to permissions, policies, versioning, and the lack of a unified, collective procedure or toolset for deploying software across all sites. Therefore, a new mechanism for data and software distributing is desirable. The architecture for the OSG Application Software Installation Service (OASIS) is a server-client model: the software and data are installed only once in a single place, and are automatically distributed to all client sites simultaneously. Central file distribution offers other advantages, including server-side authentication and authorization, activity records, quota management, data validation and inspection, and well-defined versioning and deletion policies. The architecture, as well as a complete analysis of the current implementation, will be described in this paper.

ReSS: A Resource Selection Service for the Open Science Grid  

SciTech Connect

The Open Science Grid offers access to hundreds of computing and storage resources via standard Grid interfaces. Before the deployment of an automated resource selection system, users had to submit jobs directly to these resources. They would manually select a resource and specify all relevant attributes in the job description prior to submitting the job. The necessity of a human intervention in resource selection and attribute specification hinders automated job management components from accessing OSG resources and it is inconvenient for the users. The Resource Selection Service (ReSS) project addresses these shortcomings. The system integrates condor technology, for the core match making service, with the gLite CEMon component, for gathering and publishing resource information in the Glue Schema format. Each one of these components communicates over secure protocols via web services interfaces. The system is currently used in production on OSG by the DZero Experiment, the Engagement Virtual Organization, and the Dark Energy. It is also the resource selection service for the Fermilab Campus Grid, FermiGrid. ReSS is considered a lightweight solution to push-based workload management. This paper describes the architecture, performance, and typical usage of the system.

A Science Driven Production Cyberinfrastructure-the Open Science Grid  

SciTech Connect

This article describes the Open Science Grid, a large distributed computational infrastructure in the United States which supports many different high-throughput scientific applications, and partners (federates) with other infrastructures nationally and internationally to form multi-domain integrated distributed systems for science. The Open Science Grid consortium not only provides services and software to an increasingly diverse set of scientific communities, but also fosters a collaborative team of practitioners and researchers who use, support and advance the state of the art in large-scale distributed computing. The scale of the infrastructure can be expressed by the daily throughput of around seven hundred thousand jobs, just under a million hours of computing, a million file transfers, and half a petabyte of data movement. In this paper we introduce and reflect on some of the OSG capabilities, usage and activities.

Labels Matter: Changing the Conversation From “-isms” to Privilege  

NASA Astrophysics Data System (ADS)

Whites typically view racism as discrimination and unfair judgment based on skin color. This view inhibits an end to race-based oppression because it names the issue in terms of the oppressed. A more accurate label is White Privilege. The concept of White privilege is very different from the concept of racism because it includes all Whites, not just those who hold explicit racist views. Acknowledging privilege can be threatening for those who hold a privileged status. However, it is necessary for those who are advantaged to have clarity about their status if the “isms” are to be overcome. In this talk I will discuss my personal struggle to acknowledge my own privileged status (White, American, straight, etc.) and will offer suggestions based on my own experiences for working with advantaged populations committed to overcoming all forms of oppression.

Testicular defense systems: immune privilege and innate immunity  

PubMed Central

The mammalian testis possesses a special immunological environment because of its properties of remarkable immune privilege and effective local innate immunity. Testicular immune privilege protects immunogenic germ cells from systemic immune attack, and local innate immunity is important in preventing testicular microbial infections. The breakdown of local testicular immune homeostasis may lead to orchitis, an etiological factor of male infertility. The mechanisms underlying testicular immune privilege have been investigated for a long time. Increasing evidence shows that both a local immunosuppressive milieu and systemic immune tolerance are involved in maintaining testicular immune privilege status. The mechanisms underlying testicular innate immunity are emerging based on the investigation of the pattern recognition receptor-mediated innate immune response in testicular cells. This review summarizes our current understanding of testicular defense mechanisms and identifies topics that merit further investigation. PMID:24954222

Mediated definite delegation - Certified Grid jobs in ALICE and beyond  

NASA Astrophysics Data System (ADS)

Grid computing infrastructures need to provide traceability and accounting of their users’ activity and protection against misuse and privilege escalation, where the delegation of privileges in the course of a job submission is a key concern. This work describes an improved handling of Multi-user Grid Jobs in the ALICE Grid Services. A security analysis of the ALICE Grid job model is presented with derived security objectives, followed by a discussion of existing approaches of unrestricted delegation based on X.509 proxy certificates and the Grid middleware gLExec. Unrestricted delegation has severe security consequences and limitations, most importantly allowing for identity theft and forgery of jobs and data. These limitations are discussed and formulated, both in general and with respect to an adoption in line with Multi-user Grid Jobs. A new general model of mediated definite delegation is developed, allowing a broker to dynamically process and assign Grid jobs to agents while providing strong accountability and long-term traceability. A prototype implementation allowing for fully certified Grid jobs is presented as well as a potential interaction with gLExec. The achieved improvements regarding system security, malicious job exploitation, identity protection, and accountability are emphasized, including a discussion of non-repudiation in the face of malicious Grid jobs.

Medical staff appointment and delineation of pediatric privileges in hospitals.  

PubMed

The review and verification of credentials and the granting of clinical privileges are required of every hospital to ensure that members of the medical staff are competent and qualified to provide specified levels of patient care. The credentialing process involves the following: (1) assessment of the professional and personal background of each practitioner seeking privileges; (2) assignment of privileges appropriate for the clinician's training and experience; (3) ongoing monitoring of the professional activities of each staff member; and (4) periodic reappointment to the medical staff on the basis of objectively measured performance. We examine the essential elements of a credentials review for initial and renewed medical staff appointments along with suggested criteria for the delineation of clinical privileges. Sample forms for the delineation of privileges can be found on the American Academy of Pediatrics Committee on Hospital Care Web site (http://www.aap.org/visit/cmte19.htm). Because of differences among individual hospitals, no 1 method for credentialing is universally applicable. The medical staff of each hospital must, therefore, establish its own process based on the general principles reviewed in this report. The issues of medical staff membership and credentialing have become very complex, and institutions and medical staffs are vulnerable to legal action. Consequently, it is advisable for hospitals and medical staffs to obtain expert legal advice when medical staff bylaws are constructed or revised. PMID:22451705

Progress and Privilege: A book about environmentalism meets the press  

NASA Astrophysics Data System (ADS)

In August 1982, Anchor Press published Progress and Privilege, a book by William Tucker. Tucker's thesis was that environmentalism represented “the ideas of aristocratic conservatism translated onto a popular scale,” and that it had entwined itself with the protection of social and economic privilege. The book was riddled with fundamental errors of fact and of logic, but it also was literate and superficially impressive. It was widely reviewed. An examination of 23 reviews shows this: Most of the reviews in daily newspapers were written by laymen who couldn't analyze Tucker's arguments or recognize his mistakes. Most of the reviews in specialized publications were done by competent analysts who brought some special knowledge to their work. With the latter group of reviewers, Progress and Privilege fared poorly.

The Romanian privilege in French medicine and anti-Semitism.  

PubMed

This paper reviews a special privilege given to Romanian medical students over other foreign medical students coming to study in France from the 1850s to the 1930s. It shows how, because of changing circumstances in Romania itself, this privilege evolved from benefiting small numbers of Christian students, who generally returned home after their studies, to benefiting large numbers of Jewish students, many of whom remained in France to practise medicine. It also shows how this evolution fed into medical anti-Semitism in France which discriminated specifically against these Romanian students as Jews, a phenomenon which was distinct from the French medical xenophobia directed against all foreign students.

Using Hadoop File System and MapReduce in a small/medium Grid site  

NASA Astrophysics Data System (ADS)

Data storage and data access represent the key of CPU-intensive and data-intensive high performance Grid computing. Hadoop is an open-source data processing framework that includes fault-tolerant and scalable distributed data processing model and execution environment, named MapReduce, and distributed File System, named Hadoop distributed File System (HDFS). HDFS was deployed and tested within the Open Science Grid (OSG) middleware stack. Efforts have been taken to integrate HDFS with gLite middleware. We have tested the File System thoroughly in order to understand its scalability and fault-tolerance while dealing with small/medium site environment constraints. To benefit entirely from this File System, we made it working in conjunction with Hadoop Job scheduler to optimize the executions of the local physics analysis workflows. The performance of the analysis jobs which used such architecture seems to be promising, making it useful to follow up in the future.

Non-stochastic reprogramming from a privileged somatic cell state  

PubMed Central

SUMMARY Reprogramming somatic cells to induced pluripotency by Yamanaka factors is usually slow and inefficient, and is thought to be a stochastic process. We identified a privileged somatic cell state, from which acquisition of pluripotency could occur in a non-stochastic manner. Subsets of murine hematopoietic progenitors are privileged, whose progeny cells predominantly adopt the pluripotent fate with activation of endogenous Oct4 locus after 4–5 divisions in reprogramming conditions. Privileged cells display an ultrafast cell cycle of ~8 hours. In fibroblasts, a subpopulation cycling at a similar ultrafast speed is observed after 6 days of factor expression, and is increased by p53-knockdown. This ultrafast-cycling population accounts for >99% of the bulk reprogramming activity in wildtype or p53-knockdown fibroblasts. Our data demonstrate that the stochastic nature of reprogramming can be overcome in a privileged somatic cell state, and suggest that cell cycle acceleration toward a critical threshold is an important bottleneck for reprogramming.

Automatic Integration Testbeds validation on Open Science Grid  

NASA Astrophysics Data System (ADS)

A recurring challenge in deploying high quality production middleware is the extent to which realistic testing occurs before release of the software into the production environment. We describe here an automated system for validating releases of the Open Science Grid software stack that leverages the (pilot-based) PanDA job management system developed and used by the ATLAS experiment. The system was motivated by a desire to subject the OSG Integration Testbed to more realistic validation tests. In particular those which resemble to every extent possible actual job workflows used by the experiments thus utilizing job scheduling at the compute element (CE), use of the worker node execution environment, transfer of data to/from the local storage element (SE), etc. The context is that candidate releases of OSG compute and storage elements can be tested by injecting large numbers of synthetic jobs varying in complexity and coverage of services tested. The native capabilities of the PanDA system can thus be used to define jobs, monitor their execution, and archive the resulting run statistics including success and failure modes. A repository of generic workflows and job types to measure various metrics of interest has been created. A command-line toolset has been developed so that testbed managers can quickly submit "VO-like" jobs into the system when newly deployed services are ready for testing. A system for automatic submission has been crafted to send jobs to integration testbed sites, collecting the results in a central service and generating regular reports for performance and reliability.

Fibonacci Grids  

NASA Technical Reports Server (NTRS)

Recent years have seen a resurgence of interest in a variety of non-standard computational grids for global numerical prediction. The motivation has been to reduce problems associated with the converging meridians and the polar singularities of conventional regular latitude-longitude grids. A further impetus has come from the adoption of massively parallel computers, for which it is necessary to distribute work equitably across the processors; this is more practicable for some non-standard grids. Desirable attributes of a grid for high-order spatial finite differencing are: (i) geometrical regularity; (ii) a homogeneous and approximately isotropic spatial resolution; (iii) a low proportion of the grid points where the numerical procedures require special customization (such as near coordinate singularities or grid edges). One family of grid arrangements which, to our knowledge, has never before been applied to numerical weather prediction, but which appears to offer several technical advantages, are what we shall refer to as "Fibonacci grids". They can be thought of as mathematically ideal generalizations of the patterns occurring naturally in the spiral arrangements of seeds and fruit found in sunflower heads and pineapples (to give two of the many botanical examples). These grids possess virtually uniform and highly isotropic resolution, with an equal area for each grid point. There are only two compact singular regions on a sphere that require customized numerics. We demonstrate the practicality of these grids in shallow water simulations, and discuss the prospects for efficiently using these frameworks in three-dimensional semi-implicit and semi-Lagrangian weather prediction or climate models.

Influence of Immune Privilege on Ocular Tumor Development  

PubMed Central

Mechanisms that maintain ocular immune privilege may contribute to ocular tumor progression by inhibiting tumoricidal immune responses. Consistent with that notion are observations from transplantable tumor models in mice demonstrating that the tumoricidal activity of CD8+ cytolytic T lymphocytes (CTL) may be inhibited directly by interfering with CTL effector function in the eye or indirectly by abrogating the effector function of CD8+ T cell-activated intratumoral macrophages that are critical for ocular tumor rejection. In addition, epigenetic gene regulation by factors within the ocular tumor environment favors the generation of tumor variants that are resistant to CD8+ CTL. Intratumoral macrophages may be essential for eliminating these variants because, unlike CTL, their tumoricidal activity is nonspecific. Hence, the inhibition of macrophage effector function within the eye, presumably to preserve immune privilege by minimizing ocular immunopathology, may hasten the outgrowth of tumor escape variants which contributes to ocular tumor progression.

Mesenchymal stem cells: immune evasive, not immune privileged  

PubMed Central

The diverse immunomodulatory properties of mesenchymal stem/stromal cells (MSCs) may be exploited for treatment of a multitude of inflammatory conditions. MSCs have long been reported to be hypoimmunogenic or ‘immune privileged’; this property is thought to enable MSC transplantation across major histocompatibility barriers and the creation of off-the-shelf therapies consisting of MSCs grown in culture. However, recent studies describing generation of antibodies against and immune rejection of allogeneic donor MSCs suggest that MSCs may not actually be immune privileged. Nevertheless, whether rejection of donor MSCs influences the efficacy of allogeneic MSC therapies is not known, and no definitive clinical advantage of autologous MSCs over allogeneic MSCs has been demonstrated to date. Although MSCs may exert therapeutic function through a brief ‘hit and run’ mechanism, protecting MSCs from immune detection and prolonging their persistence in vivo may improve clinical outcomes and prevent patient sensitization toward donor antigens.

The Open Science Grid - Support for Multi-Disciplinary Team Science - the Adolescent Years  

NASA Astrophysics Data System (ADS)

As it enters adolescence the Open Science Grid (OSG) is bringing a maturing fabric of Distributed High Throughput Computing (DHTC) services that supports an expanding HEP community to an increasingly diverse spectrum of domain scientists. Working closely with researchers on campuses throughout the US and in collaboration with national cyberinfrastructure initiatives, we transform their computing environment through new concepts, advanced tools and deep experience. We discuss examples of these including: the pilot-job overlay concepts and technologies now in use throughout OSG and delivering 1.4 Million CPU hours/day; the role of campus infrastructures- built out from concepts of sharing across multiple local faculty clusters (made good use of already by many of the HEP Tier-2 sites in the US); the work towards the use of clouds and access to high throughput parallel (multi-core and GPU) compute resources; and the progress we are making towards meeting the data management and access needs of non-HEP communities with general tools derived from the experience of the parochial tools in HEP (integration of Globus Online, prototyping with IRODS, investigations into Wide Area Lustre). We will also review our activities and experiences as HTC Service Provider to the recently awarded NSF XD XSEDE project, the evolution of the US NSF TeraGrid project, and how we are extending the reach of HTC through this activity to the increasingly broad national cyberinfrastructure. We believe that a coordinated view of the HPC and HTC resources in the US will further expand their impact on scientific discovery.

T cell exclusion, immune privilege, and the tumor microenvironment.  

PubMed

Effective immunotherapy promotes the killing of cancer cells by cytotoxic T cells. This requires not only that cancer-specific T cells be generated, but also that these T cells physically contact cancer cells. The coexistence in some patients of cancer cells and T cells that recognize them indicates that tumors may exhibit the phenomenon of immune privilege, in which immunogenic tissue is protected from immune attack. Here, we review the evidence that stromal cells of the tumor microenvironment mediate this restriction by excluding T cells from the vicinity of cancer cells. Overcoming this T cell checkpoint may thus enable optimal immunotherapy. PMID:25838376

Progress and privilege: America in the age of environmentalism  

SciTech Connect

Environmentalism, which was a rarity in the 1960s, approaches a national religion in the 1980s, with some environmentalists experiencing pleasure at the prospect of limited resources and no growth. The author explores this new ambivalence toward progress, and concludes that accomplishment can dampen ambition. His analysis of environmentalism as an expression of privilege examines the political and economic characteristics of environmentalists, the major environmental issues, and the public revolt against science to uncover an aristocratic element that is diappearing from our culture. Progress will continue, however, because of global ambitions. The US can build on what has been learned during the Age of Environmentalism and get on with the progress of humanity. 159 references, 1 figure. (DCK)

GridMan: A grid manipulation system  

NASA Technical Reports Server (NTRS)

GridMan is an interactive grid manipulation system. It operates on grids to produce new grids which conform to user demands. The input grids are not constrained to come from any particular source. They may be generated by algebraic methods, elliptic methods, hyperbolic methods, parabolic methods, or some combination of methods. The methods are included in the various available structured grid generation codes. These codes perform the basic assembly function for the various elements of the initial grid. For block structured grids, the assembly can be quite complex due to a large number of clock corners, edges, and faces for which various connections and orientations must be properly identified. The grid generation codes are distinguished among themselves by their balance between interactive and automatic actions and by their modest variations in control. The basic form of GridMan provides a much more substantial level of grid control and will take its input from any of the structured grid generation codes. The communication link to the outside codes is a data file which contains the grid or section of grid.

Waiver of the psychotherapist-patient privilege: implications for child custody litigation.  

PubMed

The psychotherapist-patient privilege, rooted in both common and statutory law, is predicated upon the public policy goal of protecting the reasonable expectation of privacy of individuals seeking psychotherapy. The privilege is not absolute, however. State and federal courts are far from uniform in determining how and when the privilege should be waived, in whole or in part, through implication, inadvertence or the affirmative action of the parties. In the family law context, the law that has evolved around the exercise of this privilege is even more complex as the needs of children add another wrinkle to the goal of balancing the imperative of confidentiality with the need for useful information that may be provided.

Data Grid Management Systems  

NASA Technical Reports Server (NTRS)

The "Grid" is an emerging infrastructure for coordinating access across autonomous organizations to distributed, heterogeneous computation and data resources. Data grids are being built around the world as the next generation data handling systems for sharing, publishing, and preserving data residing on storage systems located in multiple administrative domains. A data grid provides logical namespaces for users, digital entities and storage resources to create persistent identifiers for controlling access, enabling discovery, and managing wide area latencies. This paper introduces data grids and describes data grid use cases. The relevance of data grids to digital libraries and persistent archives is demonstrated, and research issues in data grids and grid dataflow management systems are discussed.

Customers' expectations of complaint handling by airline service: privilege status and reasonability of demands from a social learning perspective.  

PubMed

In the airline industry, membership and cabin class are noticeable servicescape features of customers' privilege status. Customers may learn that higher privilege customers are more desired and endured by the airline. From the customers' point of view, those with higher privilege may expect their demands to be complied with when they complain. The present study employed hypothetical scenarios to investigate how the privilege status of passengers and reasonability of their demands influenced their expectations toward the compliance of airline personnel. Analysis showed that higher privilege customers were more likely to expect airline personnel to comply with their demands. Moreover, participants with medium or high levels of privilege status had greater expectations of compliance even when demands were unreasonable. In sum, customer expectations toward complaint handling reflected predictions based on social learning. PMID:19610476

The privileged normalization of marijuana use – an analysis of Canadian newspaper reporting, 1997–2007  

PubMed Central

The objective of this study was to systematically examine predominant themes within mainstream media reporting about marijuana use in Canada. To ascertain the themes present in major Canadian newspaper reports, a sample (N = 1999) of articles published between 1997 and 2007 was analyzed. Drawing from Manning's theory of the symbolic framing of drug use within media, it is argued that a discourse of ‘privileged normalization’ informs portrayals of marijuana use and descriptions of the drug's users. Privileged normalization implies that marijuana use can be acceptable for some people at particular times and places, while its use by those without power and status is routinely vilified and linked to deviant behavior. The privileged normalization of marijuana by the media has important health policy implications in light of continued debate regarding the merits of decriminalization or legalization and the need for public health and harm reduction approaches to illicit drug use.

Unruly democracy and the privileges of public intimacy: (same) sex spousal hiring in academia.

Within the context of a discussion of lesbian academic couples there is something to be said about the (dis)pleasures and profits of a heteronormative practice such as spousal hiring and how much this privilege reveals the broader systemic discrimination vis-à-vis sexual and gender claims in our academic institutions. Two issues emerge from its (questionable) application: (1) How a privilege such as spousal hiring intersects with institutional policies concerning sexual diversity; and in light of this, (2)Why queer or lesbian couples shouldn't embrace dubious spousal hiring incentives.

RBAC Driven Least Privilege Architecture For Control Systems  

SciTech Connect

The concept of role based access control (RBAC) within the IT environment has been studied by researchers and was supported by NIST (circa 1992). This earlier work highlighted the benefits of RBAC which include reduced administrative workload and policies which are easier to analyze and apply. The goals of this research were to expand the application of RBAC in the following ways. • Apply RBAC to the control systems environment: The typical RBAC model within the IT environment is used to control a user’s access to files. Within the control system environment files are replaced with measurement (e.g., temperature) and control (e.g. valve) points organized as a hierarchy of control assets (e.g. a boiler, compressor, refinery unit). Control points have parameters (e.g., high alarm limit, set point, etc.) associated with them. The RBAC model is extended to support access to points and their parameters based upon roles while at the same time allowing permissions for the points to be defined at the asset level or point level directly. In addition, centralized policy administration with distributed access enforcement mechanisms was developed to support the distributed architecture of distributed control systems and SCADA. • Extend the RBAC model to include access control for software and devices: The established RBAC approach is to assign users to roles. This work extends that notion by first breaking the control system down into three layers 1) users, 2) software and 3) devices. An RBAC model is then created for each of these three layers. The result is that RBAC can be used to define machine-to-machine policy enforced via the IP security (IPsec) protocol. This highlights the potential to use RBAC for machine-to-machine connectivity within the internet of things. • Enable dynamic policy based upon the operating mode of the system: The IT environment is generally static with respect to policy. However, large cyber physical systems such as industrial controls have various operating modes (start-up, normal operation, emergency, shut-down and maintenance are typical). The policy enforcement architecture must be able to support changes in access permissions as the mode of the control system changes. For example an operator’s role may not allow the operator to shut down a pump during “normal operation” but that same operator role may be given permission to shut down the pump if the refinery transitions to “emergency” mode. The effectiveness of the approach was validated by applying it to the Experion Process Knowledge System. This is a large commercial industrial control system often used to control oil refineries and other assets within the oil and gas sector. As a by-product, other industries using Experion (Pharmaceuticals, Specialty Chemicals, etc.) also benefit from increased security. Policies representative of those that would be used within an oil refinery were created and validated against the RBAC model as implemented in the underlying SQL database. The administration of policy is simplified which in turn makes it practical for security administrators to specify policies which enforce least privilege. The result is a qualitative reduction in risk. The benefits of the enhanced RBAC model are clear and as a result. Honeywell is incorporating portions of the RBAC research into the 2014 release of Experion.

Chimera Grid Tools  

NASA Technical Reports Server (NTRS)

Chimera Grid Tools (CGT) is a software package for performing computational fluid dynamics (CFD) analysis utilizing the Chimera-overset-grid method. For modeling flows with viscosity about geometrically complex bodies in relative motion, the Chimera-overset-grid method is among the most computationally cost-effective methods for obtaining accurate aerodynamic results. CGT contains a large collection of tools for generating overset grids, preparing inputs for computer programs that solve equations of flow on the grids, and post-processing of flow-solution data. The tools in CGT include grid editing tools, surface-grid-generation tools, volume-grid-generation tools, utility scripts, configuration scripts, and tools for post-processing (including generation of animated images of flows and calculating forces and moments exerted on affected bodies). One of the tools, denoted OVERGRID, is a graphical user interface (GUI) that serves to visualize the grids and flow solutions and provides central access to many other tools. The GUI facilitates the generation of grids for a new flow-field configuration. Scripts that follow the grid generation process can then be constructed to mostly automate grid generation for similar configurations. CGT is designed for use in conjunction with a computer-aided-design program that provides the geometry description of the bodies, and a flow-solver program.

The tool allows the user to explore the grid space and to navigate the execution at a grid application to minimize its turnaround time. We introduce the notion of gridscape as a user view of the grid and show how it can be me assured by NGB, Then we demonstrate how the gridscape can be used with two different schedulers to navigate a grid application through a rudimentary grid.

The role of attitudes toward White privilege and religious beliefs in predicting social justice interest and commitment.  

PubMed

The current study examines links among attitudes toward White privilege, religious beliefs, and social justice interest and commitment for White Christian students. Two distinct patterns of results emerged from a path analysis of 500 White Christian students. First, a willingness to confront White privilege was positively associated with the sanctification of social justice (i.e., attributing spiritual significance to working for social justice) and both were positively associated with social justice interest and commitment. Second, awareness of White privilege was negatively associated with religious conservatism, and religious conservatism was negatively associated with social justice interest. These patterns show that White privilege attitudes directly (i.e., willingness to confront White privilege) and indirectly (i.e., awareness of White privilege through religious conservatism) predicted social justice interest and commitment. Moreover, religious beliefs demonstrated opposite patterns of association with social justice interest and commitment such that the sanctification of social justice positively predicted social justice interest and commitment whereas religious conservatism negatively predicted social justice interest. Overall, findings demonstrate direct and indirect links between White privilege attitudes, religious beliefs, and social justice interest and commitment. Limitations and implications for future community psychology research and collaboration also are discussed. PMID:24473921

Securing smart grid technology  

NASA Astrophysics Data System (ADS)

In the developing countries electrical energy is very important for its all-round improvement by saving thousands of dollars and investing them in other sector for development. For Growing needs of power existing hierarchical, centrally controlled grid of the 20th Century is not sufficient. To produce and utilize effective power supply for industries or people we should have Smarter Electrical grids that address the challenges of the existing power grid. The Smart grid can be considered as a modern electric power grid infrastructure for enhanced efficiency and reliability through automated control, high-power converters, modern communications infrastructure along with modern IT services, sensing and metering technologies, and modern energy management techniques based on the optimization of demand, energy and network availability and so on. The main objective of this paper is to provide a contemporary look at the current state of the art in smart grid communications as well as critical issues on smart grid technologies primarily in terms of information and communication technology (ICT) issues like security, efficiency to communications layer field. In this paper we propose new model for security in Smart Grid Technology that contains Security Module(SM) along with DEM which will enhance security in Grid. It is expected that this paper will provide a better understanding of the technologies, potential advantages and research challenges of the smart grid and provoke interest among the research community to further explore this promising research area.

Grid enabled Service Support Environment - SSE Grid  

NASA Astrophysics Data System (ADS)

The SSEGrid project is an ESA/ESRIN project which started in 2009 and is executed by two Belgian companies, Spacebel and VITO, and one Dutch company, Dutch Space. The main project objectives are the introduction of a Grid-based processing on demand infrastructure at the Image Processing Centre for earth observation products at VITO and the inclusion of Grid processing services in the Service Support Environment (SSE) at ESRIN. The Grid-based processing on demand infrastructure is meant to support a Grid processing on demand model for Principal Investigators (PI) and allow the design and execution of multi-sensor applications with geographically spread data while minimising the transfer of huge volumes of data. In the first scenario, 'support a Grid processing on demand model for Principal Investigators', we aim to provide processing power close to the EO-data at the processing and archiving centres. We will allow a PI (non-Grid expert user) to upload his own algorithm, as a process, and his own auxiliary data from the SSE Portal and use them in an earth observation workflow on the SSEGrid Infrastructure. The PI can design and submit workflows using his own processes, processes made available by VITO/ESRIN and possibly processes from other users that are available on the Grid. These activities must be user-friendly and not requiring detailed knowledge about the underlying Grid middleware. In the second scenario we aim to design, implement and demonstrate a methodology to set up an earth observation processing facility, which uses large volumes of data from various geographically spread sensors. The aim is to provide solutions for problems that we face today, like wasting bandwidth by copying large volumes of data to one location. We will avoid this by processing the data where they are. The multi-mission Grid-based processing on demand infrastructure will allow developing and executing complex and massive multi-sensor data (re-)processing applications more efficiently. A workflow can be built and submitted for execution on multiple loosely coupled Grids (e.g. at VITO and at ESRIN). It is ensured that the data are processed where they are located. For this purpose the project aims to upgrade the Service Support Environment (SSE) to integrate multi-Grid processing services to be used by the PI for the systematic processing or reprocessing of EO data. For both scenarios described above, two processing modes will be available. In near real-time (NRT), or 'subscription mode', processing, the execution of a workflow is started but suspended a certain step where the workflow waits until certain data are present on the Grid. As soon as the data become available from the sensors, the execution is resumed automatically. In 'historical mode' it is assumed that the data are already present. An other main objective of the SSEGrid project is to propose new or amended versions of 'Web Processing Service' protocols that may be able to bridge geo-spatial Service Oriented Architectures and Open Grid Services Architectures. In this context we will propose the Grid Web Processing Service as an extension of the OGC WPS service to allow for the dynamic deployment of user processes (workflows or Grid processes) and auxiliary data, for the discovery of user auxiliary data, for the query of process status and process audit (execution trace, log file) and for the notification of process completion or failure.

Today's global communities of users expect quality of service from distributed Grid systems equivalent to that their local data centers. This must be coupled to ubiquitous access to the ensemble of processing and storage resources across multiple Grid infrastructures. We are still facing significant challenges in meeting these expectations, especially in the underlying security, a sustainable and successful economic model, and smoothing the boundaries between administrative and technical domains.

Enhanced Elliptic Grid Generation  

NASA Technical Reports Server (NTRS)

An enhanced method of elliptic grid generation has been invented. Whereas prior methods require user input of certain grid parameters, this method provides for these parameters to be determined automatically. "Elliptic grid generation" signifies generation of generalized curvilinear coordinate grids through solution of elliptic partial differential equations (PDEs). Usually, such grids are fitted to bounding bodies and used in numerical solution of other PDEs like those of fluid flow, heat flow, and electromagnetics. Such a grid is smooth and has continuous first and second derivatives (and possibly also continuous higher-order derivatives), grid lines are appropriately stretched or clustered, and grid lines are orthogonal or nearly so over most of the grid domain. The source terms in the grid-generating PDEs (hereafter called "defining" PDEs) make it possible for the grid to satisfy requirements for clustering and orthogonality properties in the vicinity of specific surfaces in three dimensions or in the vicinity of specific lines in two dimensions. The grid parameters in question are decay parameters that appear in the source terms of the inhomogeneous defining PDEs. The decay parameters are characteristic lengths in exponential- decay factors that express how the influences of the boundaries decrease with distance from the boundaries. These terms govern the rates at which distance between adjacent grid lines change with distance from nearby boundaries. Heretofore, users have arbitrarily specified decay parameters. However, the characteristic lengths are coupled with the strengths of the source terms, such that arbitrary specification could lead to conflicts among parameter values. Moreover, the manual insertion of decay parameters is cumbersome for static grids and infeasible for dynamically changing grids. In the present method, manual insertion and user specification of decay parameters are neither required nor allowed. Instead, the decay parameters are determined automatically as part of the solution of the defining PDEs. Depending on the shape of the boundary segments and the physical nature of the problem to be solved on the grid, the solution of the defining PDEs may provide for rates of decay to vary along and among the boundary segments and may lend itself to interpretation in terms of one or more physical quantities associated with the problem.

Privileged structures: efficient chemical "navigators" toward unexplored biologically relevant chemical spaces.  

PubMed

In the search for new therapeutic agents for currently incurable diseases, attention has turned to traditionally "undruggable" targets, and collections of drug-like small molecules with high diversity and quality have become a prerequisite for new breakthroughs. To generate such collections, the diversity-oriented synthesis (DOS) strategy was developed, which aims to populate new chemical space with drug-like compounds containing a high degree of molecular diversity. The resulting DOS-derived libraries have been of great value for the discovery of various bioactive small molecules and therapeutic agents, and thus DOS has emerged as an essential tool in chemical biology and drug discovery. However, the key challenge has become how to design and synthesize drug-like small-molecule libraries with improved biological relevancy as well as maximum molecular diversity. This Perspective presents the development of privileged substructure-based DOS (pDOS), an efficient strategy for the construction of polyheterocyclic compound libraries with high biological relevancy. We envisioned the specific interaction of drug-like small molecules with certain biopolymers via the incorporation of privileged substructures into polyheterocyclic core skeletons. The importance of privileged substructures such as benzopyran, pyrimidine, and oxopiperazine in rigid skeletons was clearly demonstrated through the discovery of bioactive small molecules and the subsequent identification of appropriate target biomolecule using a method called "fluorescence difference in two-dimensional gel electrophoresis". Focusing on examples of pDOS-derived bioactive compounds with exceptional specificity, we discuss the capability of privileged structures to serve as chemical "navigators" toward biologically relevant chemical spaces. We also provide an outlook on chemical biology research and drug discovery using biologically relevant compound libraries constructed by pDOS, biology-oriented synthesis, or natural product-inspired DOS.

Parental Reasoning, Denying Privileges, Yelling, and Spanking: Ethnic Differences and Associations with Child Externalizing Behavior  

PubMed Central

Synopsis Objective This study was designed to examine whether African American and European American mothers differ in their discipline use when reasoning, denying privileges, yelling, and spanking are considered simultaneously and whether there are ethnic group differences in how these four forms of discipline are associated with child externalizing behavior. Design Structural equation models were used to examine relations between children's externalizing behavior in kindergarten (age 5), mothers' discipline in grades 1-3 (ages 6-8), and children's externalizing behavior in grade 4 (age 9) in a sample of 585 mothers and children. Results African American and European American mothers showed the same rank order frequency of reported use of each of the four forms of discipline, most frequently using reasoning, followed by yelling, denying privileges, and least frequently spanking. However, European American mothers more frequently reported using three of the four forms of discipline than did African American mothers, with no ethnic differences in the frequency with which mothers reported spanked. For European American children, higher levels of teacher-reported child externalizing in kindergarten predicted mothers' more frequent report of denying privileges, yelling, and spanking in grades 1-3; only spanking was associated with more child externalizing behaviors in grade 4. For African American children, teacher-reported child externalizing in kindergarten was unrelated to mothers' report of discipline in grades 1-3; considering predictions from discipline to grade 4 child externalizing, only denying privileges was predictive. Conclusions European American and African American families differ in links between children's teacher-reported externalizing behaviors and subsequent mother-reported discipline as well as links between mother-reported discipline and children's subsequent teacher-reported externalizing.

Preferences for clinic privileges, retail items and social activities in an outpatient buprenorphine treatment program.  

PubMed

This study evaluated preferences for various clinic privileges, retail items, and social activities for use in an outpatient opioid dependence treatment program. Fifty-three opioid-dependent patients who received treatment with buprenorphine for at least 30 days rank ordered 11 clinic privileges, 19 retail items, and 8 social activities from the most desirable (a rank of 1) to the least desirable (a rank equal to the number of items in that category). Additional questions determined preference for counseling frequency and dosing levels. The top three mean rankings for clinic privileges were $50 cash for opioid-negative urines (2.8), take-home doses of buprenorphine (3.6), and voucher points for opioid-negative urines (4.7). The top three mean rankings for retail items were restaurant gift certificates (4.1), movie passes (4.9), and videotape movie and player rentals (6.8). The top three mean rankings for social activities were movies (2.4), barbecues (3.8), and hiking trips (4.3). There was no preference reported for increases or decreases in counseling frequency. Seventy-four percent of subjects preferred to increase their buprenorphine dose by an average of 60.84% independent of their present dose. Consistent with previous findings from methadone treatment, cash payments for opioid-negative urines and take-home medication were the highest ranked clinic privileges. These results suggest that various retail items and social activities may also be useful for reinforcing positive treatment outcomes during outpatient opioid treatment. PMID:8699542

Immune privilege of the CNS is not the consequence of limited antigen sampling  

NASA Astrophysics Data System (ADS)

Central nervous system (CNS) immune privilege is complex, and it is still not understood how CNS antigens are sampled by the peripheral immune system under steady state conditions. To compare antigen sampling from immune-privileged or nonprivileged tissues, we created transgenic mice with oligodendrocyte or gut epithelial cell expression of an EGFP-tagged fusion protein containing ovalbumin (OVA) antigenic peptides and tested peripheral anti-OVA peptide-specific sentinel OT-I and OT-II T cell activation. We report that oligodendrocyte or gut antigens are sampled similarly, as determined by comparable levels of OT-I T cell activation. However, activated T cells do not access the CNS under steady state conditions. These data show that afferent immunity is normally intact as there is no barrier at the antigen sampling level, but that efferent immunity is restricted. To understand how this one-sided surveillance contributes to CNS immune privilege will help us define mechanisms of CNS autoimmune disease initiation.

Decentral Smart Grid Control  

NASA Astrophysics Data System (ADS)

Stable operation of complex flow and transportation networks requires balanced supply and demand. For the operation of electric power grids—due to their increasing fraction of renewable energy sources—a pressing challenge is to fit the fluctuations in decentralized supply to the distributed and temporally varying demands. To achieve this goal, common smart grid concepts suggest to collect consumer demand data, centrally evaluate them given current supply and send price information back to customers for them to decide about usage. Besides restrictions regarding cyber security, privacy protection and large required investments, it remains unclear how such central smart grid options guarantee overall stability. Here we propose a Decentral Smart Grid Control, where the price is directly linked to the local grid frequency at each customer. The grid frequency provides all necessary information about the current power balance such that it is sufficient to match supply and demand without the need for a centralized IT infrastructure. We analyze the performance and the dynamical stability of the power grid with such a control system. Our results suggest that the proposed Decentral Smart Grid Control is feasible independent of effective measurement delays, if frequencies are averaged over sufficiently large time intervals.

Running tightly coupled parallel MPI applications in a real grid environment using distributed MPI implementations (1, 2) can, in principle, make better and more fle xible use of computational resources, but for most parallel applications it has a major downside: The performance of such codes tends to be very poor. Most often the natural characteristics of realworld grids are responsible

Security for grids  

SciTech Connect

Securing a Grid environment presents a distinctive set of challenges. This paper groups the activities that need to be secured into four categories: naming and authentication; secure communication; trust, policy, and authorization; and enforcement of access control. It examines the current state of the art in securing these processes and introduces new technologies that promise to meet the security requirements of Grids more completely.

Data Grid Implementations  

SciTech Connect

Data grids link distributed, heterogeneous storage resources into a coherent data management system. From a user perspective, the data grid provides a uniform name space across the underlying storage systems, while supporting retrieval and storage of files. In the high energy physics community, at least six data grids have been implemented for the storage and distribution of experimental data. Data grids are also being used to support projects as diverse as digital libraries (National Library of Medicine Visible Embryo project), federation of multiple astronomy sky surveys (NSF National Virtual Observatory project), and integration of distributed data sets (Long Term Ecological Reserve). Data grids also form the core interoperability mechanisms for creating persistent archives, in which data collections are migrated to new technologies over time. The ability to provide a uniform name space across multiple administration domains is becoming a critical component of national-scale, collaborative projects.

Transforming Power Grid Operations  

SciTech Connect

While computation is used to plan, monitor, and control power grids, some of the computational technologies now used are more than a hundred years old, and the complex interactions of power grid components impede real-time operations. Thus it is hard to speed up “state estimation,” the procedure used to estimate the status of the power grid from measured input. State estimation is the core of grid operations, including contingency analysis, automatic generation control, and optimal power flow. How fast state estimation and contingency analysis are conducted (currently about every 5 minutes) needs to be increased radically so the analysis of contingencies is comprehensive and is conducted in real time. Further, traditional state estimation is based on a power flow model and only provides a static snapshot—a tiny piece of the state of a large-scale dynamic machine. Bringing dynamic aspects into real-time grid operations poses an even bigger challenge. Working with the latest, most advanced computing techniques and hardware, researchers at Pacific Northwest National Laboratory (PNNL) intend to transform grid operations by increasing computational speed and improving accuracy. Traditional power grid computation is conducted on single PC hardware platforms. This article shows how traditional power grid computation can be reformulated to take advantage of advanced computing techniques and be converted to high-performance computing platforms (e.g., PC clusters, reconfigurable hardware, scalable multicore shared memory computers, or multithreaded architectures). The improved performance is expected to have a huge impact on how power grids are operated and managed and ultimately will lead to more reliability and better asset utilization to the power industry. New computational capabilities will be tested and demonstrated on the comprehensive grid operations platform in the Electricity Infrastructure Operations Center, which is a newly commissioned PNNL facility for research, development and demonstration of next-generation tools and technologies for enhanced energy infrastructure operations (EIOC sidebar).

``Yin-Yang grid'': An overset grid in spherical geometry  

NASA Astrophysics Data System (ADS)

A new kind of overset grid, named Yin-Yang grid, for spherical geometry is proposed. The Yin-Yang grid is composed of two identical component grids that are combined in a complemental way to cover a spherical surface with partial overlap on their boundaries. Each component grid is a low-latitude part of the latitude-longitude grid. Therefore the grid spacing is quasi-uniform, and the metric tensors are simple and analytically known. One can directly apply mathematical and numerical resources that have been written in the spherical polar coordinates or latitude-longitude grid. The complemental combination of the two identical component grids enables us to make efficient and concise programs. Simulation codes for geodynamo and mantle convection simulations using finite difference scheme based on the Yin-Yang grid are developed and tested. The Yin-Yang grid is suitable for massively parallel computers.

Trends in life science grid: from computing grid to knowledge grid  

PubMed Central

Background Grid computing has great potential to become a standard cyberinfrastructure for life sciences which often require high-performance computing and large data handling which exceeds the computing capacity of a single institution. Results This survey reviews the latest grid technologies from the viewpoints of computing grid, data grid and knowledge grid. Computing grid technologies have been matured enough to solve high-throughput real-world life scientific problems. Data grid technologies are strong candidates for realizing "resourceome" for bioinformatics. Knowledge grids should be designed not only from sharing explicit knowledge on computers but also from community formulation for sharing tacit knowledge among a community. Conclusion Extending the concept of grid from computing grid to knowledge grid, it is possible to make use of a grid as not only sharable computing resources, but also as time and place in which people work together, create knowledge, and share knowledge and experiences in a community.

The DESY Grid Centre  

NASA Astrophysics Data System (ADS)

DESY is one of the world-wide leading centers for research with particle accelerators, synchrotron light and astroparticles. DESY participates in LHC as a Tier-2 center, supports on-going analyzes of HERA data, is a leading partner for ILC, and runs the National Analysis Facility (NAF) for LHC and ILC in the framework of the Helmholtz Alliance, Physics at the Terascale. For the research with synchrotron light major new facilities are operated and built (FLASH, PETRA-III, and XFEL). DESY furthermore acts as Data-Tier1 centre for the Neutrino detector IceCube. Established within the EGI-project DESY operates a grid infrastructure which supports a number of virtual Organizations (VO), incl. ATLAS, CMS, and LHCb. Furthermore, DESY hosts some of HEP and non-HEP VOs, such as the HERA experiments and ILC as well as photon science communities. The support of the new astroparticle physics VOs IceCube and CTA is currently set up. As the global structure of the grid offers huge resources which are perfect for batch-like computing, DESY has set up the National Analysis Facility (NAF) which complements the grid to allow German HEP users for efficient data analysis. The grid infrastructure and the NAF use the same physics data which is distributed via the grid. We call the conjunction of grid and NAF the DESY Grid Centre. In the contribution to CHEP2012 we will in depth discuss the conceptional and operational aspects of our multi-VO and multi-community Grid Centre and present the system setup. We will in particular focus on the interplay of Grid and NAF and present experiences of the operations.

Surface grid generation for multi-block structured grids  

NASA Astrophysics Data System (ADS)

A new grid generation technique for the computation of a structured grid on a generally curved surface in 3D is discussed. The starting assumption is that the parameterization of the surface exists, i.e. a smooth geometrical shape function exists which maps the parametric space (the unit square) one-to-one on the surface. The grid generation system computes a grid on the surface with as boundary conditions the following data specified along the four edges of the surface: (1) the position of the boundary grid points, (2) the grid line slopes at the boundary grid points, (3) the first grid cell lengths at the boundary grid points. The fourth-order elliptic biharmonic equations are used to compute the two families of grid lines in the parametric space. After that, each grid point in the parametric space is found as the intersection point between two individual grid lines, one from each family. The grid points on the surface are finally found by mapping the grid points in the parametric space on the surface via the geometrical shape function. Results are shown for an O-type 2D Euler grid, a C-type 2D Navier-Stokes grid and on some curved surfaces in 3D space.

Using Grid Benchmarks for Dynamic Scheduling of Grid Applications  

NASA Technical Reports Server (NTRS)

Navigation or dynamic scheduling of applications on computational grids can be improved through the use of an application-specific characterization of grid resources. Current grid information systems provide a description of the resources, but do not contain any application-specific information. We define a GridScape as dynamic state of the grid resources. We measure the dynamic performance of these resources using the grid benchmarks. Then we use the GridScape for automatic assignment of the tasks of a grid application to grid resources. The scalability of the system is achieved by limiting the navigation overhead to a few percent of the application resource requirements. Our task submission and assignment protocol guarantees that the navigation system does not cause grid congestion. On a synthetic data mining application we demonstrate that Gridscape-based task assignment reduces the application tunaround time.

Implementing Production Grids  

NASA Technical Reports Server (NTRS)

We have presented the essence of experience gained in building two production Grids, and provided some of the global context for this work. As the reader might imagine, there were a lot of false starts, refinements to the approaches and to the software, and several substantial integration projects (SRB and Condor integrated with Globus) to get where we are today. However, the point of this paper is to try and make it substantially easier for others to get to the point where Information Power Grids (IPG) and the DOE Science Grids are today. This is what is needed in order to move us toward the vision of a common cyber infrastructure for science. The author would also like to remind the readers that this paper primarily represents the actual experiences that resulted from specific architectural and software choices during the design and implementation of these two Grids. The choices made were dictated by the criteria laid out in section 1. There is a lot more Grid software available today that there was four years ago, and various of these packages are being integrated into IPG and the DOE Grids. However, the foundation choices of Globus, SRB, and Condor would not be significantly different today than they were four years ago. Nonetheless, if the GGF is successful in its work - and we have every reason to believe that it will be - then in a few years we will see that the 28 functions provided by these packages will be defined in terms of protocols and MIS, and there will be several robust implementations available for each of the basic components, especially the Grid Common Services. The impact of the emerging Web Grid Services work is not yet clear. It will likely have a substantial impact on building higher level services, however it is the opinion of the author that this will in no way obviate the need for the Grid Common Services. These are the foundation of Grids, and the focus of almost all of the operational and persistent infrastructure aspects of Grids.

IDL Grid Web Portal  

NASA Astrophysics Data System (ADS)

Image Data Language is a software for data analysis, visualization and cross-platform application development. The potentiality of IDL is well-known in the academic scientific world, especially in the astronomical environment where thousands of procedures are developed by using IDL. The typical use of IDL is the interactive mode but it is also possible to run IDL programs that do not require any interaction with the user, submitting them in batch or background modality. Through the interactive mode the user immediately receives images or other data produced in the running phase of the program; in batch or background mode, the user will have to wait for the end of the program, sometime for many hours or days to obtain images or data that IDL produced as output: in fact in Grid environment it is possible to access to or retrieve data only after completion of the program. The work that we present gives flexibility to IDL procedures submitted to the Grid computer infrastructure. For this purpose we have developed an IDL Grid Web Portal to allow the user to access the Grid and to submit IDL programs granting a full job control and the access to images and data generated during the running phase, without waiting for their completion. We have used the PHP technology and we have given the same level of security that Grid normally offers to its users. In this way, when the user notices that the intermediate program results are not those expected, he can stop the job, change the parameters to better satisfy the computational algorithm and resubmit the program, without consuming the CPU time and other Grid resources. The IDL Grid Web Portal allows you to obtain IDL generated images, graphics and data tables by using a normal browser. All conversations from the user and the Grid resources occur via Web, as well as authentication phases. The IDL user has not to change the program source much because the Portal will automatically introduce the appropriate modification before submitting the IDL program to the Grid. When the user wishes, he will be able to check the status of his program and outputs, if any, because the Portal will assign the users a specific and univocal session identification number. This Web portal runs in the Trinacria Grid Virtual Laboratory and fully exploits the power of this grid in terms of CPU and data storage.

Surgical denervation of ocular sympathetic afferents decreases local transforming growth factor-beta and abolishes immune privilege.  

PubMed

Mounting evidence points to a role for the sympathetic nervous system in suppressing inflammation. This role might be of specific relevance for immune privilege in the eye, where, sporadically, patients with denervated sympathetic fibers develop chronic inflammation. The present study used mice to investigate whether the robust innervation of intraocular structures by the sympathetic system plays a role in maintaining ocular immune privilege. We first performed surgical removal of the superior cervical ganglion, which supplies sympathetic fibers to the eye, and studied the immune response generated against soluble antigens or allogeneic tumor cells injected into the ocular anterior chamber under these conditions. Our results show that in the absence of functional sympathetic fibers, the eye loses its ability to prevent either the immune rejection of intraocular allogeneic tumor cells or the suppression of delayed type hypersensitivity responses against soluble antigens injected in the anterior chamber. This loss of immune privilege is accompanied by a decrease in the concentration of transforming growth factor-beta in the aqueous humor. These results suggest that immune privilege is lost in the absence of a functional sympathetic innervation of the eye, allowing intraocular immune responses to become exaggerated. We conclude that ocular sympathetic nerves are critical for the generation and maintenance of immune privilege in the eye through the facilitation of local transforming growth factor-beta production.

The initial federal funding for the Colorado State University Smart Grid Integration Laboratory is through a Congressionally Directed Project (CDP), DE-OE0000070 Smart Grid Integration Laboratory. The original program requested in three one-year increments for staff acquisition, curriculum development, and instrumentation â?? all which will benefit the Laboratory. This report focuses on the initial phase of staff acquisition which was directed and administered by DOE NETL/ West Virginia under Project Officer Tom George. Using this CDP funding, we have developed the leadership and intellectual capacity for the SGIC. This was accomplished by investing (hiring) a core team of Smart Grid Systems engineering faculty focused on education, research, and innovation of a secure and smart grid infrastructure. The Smart Grid Integration Laboratory will be housed with the separately funded Integrid Laboratory as part of CSUâ??s overall Smart Grid Integration Center (SGIC). The period of performance of this grant was 10/1/2009 to 9/30/2011 which included one no cost extension due to time delays in faculty hiring. The Smart Grid Integration Laboratoryâ??s focus is to build foundations to help graduate and undergraduates acquire systems engineering knowledge; conduct innovative research; and team externally with grid smart organizations. Using the results of the separately funded Smart Grid Workforce Education Workshop (May 2009) sponsored by the City of Fort Collins, Northern Colorado Clean Energy Cluster, Colorado State University Continuing Education, Spirae, and Siemens has been used to guide the hiring of faculty, program curriculum and education plan. This project develops faculty leaders with the intellectual capacity to inspire its students to become leaders that substantially contribute to the development and maintenance of Smart Grid infrastructure through topics such as: (1) Distributed energy systems modeling and control; (2) Energy and power conversion; (3) Simulation of electrical power distribution system that integrates significant quantities of renewable and distributed energy resources; (4) System dynamic modeling that considers end-user behavior, economics, security and regulatory frameworks; (5) Best practices for energy management IT control solutions for effective distributed energy integration (including security with the underlying physical power systems); (6) Experimental verification of effects of various arrangements of renewable generation, distributed generation and user load types along with conventional generation and transmission. Understanding the core technologies for enabling them to be used in an integrated fashion within a distribution network remains is a benefit to the future energy paradigm and future and present energy engineers.

Complex Volume Grid Generation Through the Use of Grid Reusability  

NASA Technical Reports Server (NTRS)

This paper presents a set of surface and volume grid generation techniques which reuse existing surface and volume grids. These methods use combinations of data manipulations to reduce grid generation time, improve grid characteristics, and increase the capabilities of existing domain discretization software. The manipulation techniques utilize physical and computational domains to produce basis function on which to operate and modify grid character and smooth grids using Trans-Finite Interpolation, a vector interpolation method and parametric re-mapping technique. With these new techniques, inviscid grids can be converted to viscous grids, multiple zone grid adaption can be performed to improve CFD solver efficiency, and topological changes to improve modeling of flow fields can be done simply and quickly. Examples of these capabilities are illustrated as applied to various configurations.

This piece poses cultural appropriation as an undertheorized aspect of white privilege in White Privilege Studies. By way of narrative exploration, it asserts that a paucity of scholarship on Orientalism and anti-Asian racism has created a gap in White Privilege Studies that curbs its radical transformative potential. It argues for the value of a structural and historically focused lens for understanding the issue of cultural appropriation, and extends questions of culture and race relations beyond the borders of the United States. It also explores the complex ways that interracial and transnational relationships can influence white racial identity, and illustrates the disruptive potential that queer interracial relationships can offer to dominant historical patterns of white behavior.

Privileged status of the subcutaneous site for skin allografts in rats.  

PubMed

Evidence is presented that in rats the subcutaneous site can extend privilege to both major histocompatibility complex (MHC)-incompatible (FI X DA)F1 leads to FI and MHC-compatible LEW leads to FI skin allografts, approximately doubling the median survival time of similar grafts transplanted orthotopically. Unlike graft dosage, "gene" dosage was an important variable in that grafts from (FI X DA)F1 donors significantly outlived those from DA strain donors. Prior splenectomy of the hosts did not prejudice the capacity of their subcutaneous sites to extend privilege. It was found that the hemagglutinin response incited by subcutaneous grafts was significantly delayed compared with that evoked by similar grafts transplanted orthotopically or intraperitoneally. This observation, coupled with our inability to demonstrate the passage of India ink to regional lymph nodes after its injection into the dermis of established subcutaneous grafts of syngenic skin, is consistent with the concept that poor endowment of the subcutaneous milieu with both blood and lymph vessels is the principal factor underlying its hospitality to allografts.

NREL Smart Grid Projects  

SciTech Connect

Although implementing Smart Grid projects at the distribution level provides many advantages and opportunities for advanced operation and control, a number of significant challenges must be overcome to maintain the high level of safety and reliability that the modern grid must provide. For example, while distributed generation (DG) promises to provide opportunities to increase reliability and efficiency and may provide grid support services such as volt/var control, the presence of DG can impact distribution operation and protection schemes. Additionally, the intermittent nature of many DG energy sources such as photovoltaics (PV) can present a number of challenges to voltage regulation, etc. This presentation provides an overview a number of Smart Grid projects being performed by the National Renewable Energy Laboratory (NREL) along with utility, industry, and academic partners. These projects include modeling and analysis of high penetration PV scenarios (with and without energy storage), development and testing of interconnection and microgrid equipment, as well as the development and implementation of advanced instrumentation and data acquisition used to analyze the impacts of intermittent renewable resources. Additionally, standards development associated with DG interconnection and analysis as well as Smart Grid interoperability will be discussed.

The Computing Grids  

NASA Astrophysics Data System (ADS)

Since the beginning of the millennium, High Energy Physics research institutions like CERN and INFN pioneered several projects aimed at exploiting the synergy among computing power, storage and network resources, and creating an infrastructure of distributed computing on a worldwide scale. In the year 2000, after the Monarch project [ http://monarc.web.cern.ch/MONARC/], DataGrid started [ http://eu-datagrid.web.cern.ch/eu-datagrid/] aimed at providing High Energy Physics with the computing power needed for the LHC enterprise. This program evolved into the EU DataGrid project, that implemented the first actual prototype of a Grid middleware running on a testbed environment. The next step consisted in the application to the LHC experiments, with the LCG project [ http://lcg.web.cern.ch/LCG/], in turn followed by the EGEE [ http://www.eu-egee.org/] and EGEE II programs.

The Global Grid  

E-print Network

This paper puts forward the vision that a natural future stage of the electricity network could be a grid spanning the whole planet and connecting most of the large power plants in the world: this is the "Global Grid". The main driving force behind the Global Grid will be the harvesting of remote renewable sources, and its key infrastructure element will be the high capacity long transmission lines. Wind farms and solar power plants will supply load centers with green power over long distances. This paper focusses on the introduction of the concept, showing that a globally interconnected network can be technologically feasible and economically competitive. We further highlight the multiple opportunities emerging from a global electricity network such as smoothing the renewable energy supply and electricity demand, reducing the need for bulk storage, and reducing the volatility of the energy prices. We also discuss possible investment mechanisms and operating schemes. Among others, we envision in such a system...

Distributed Accounting on the Grid  

NASA Technical Reports Server (NTRS)

By the late 1990s, the Internet was adequately equipped to move vast amounts of data between HPC (High Performance Computing) systems, and efforts were initiated to link together the national infrastructure of high performance computational and data storage resources together into a general computational utility 'grid', analogous to the national electrical power grid infrastructure. The purpose of the Computational grid is to provide dependable, consistent, pervasive, and inexpensive access to computational resources for the computing community in the form of a computing utility. This paper presents a fully distributed view of Grid usage accounting and a methodology for allocating Grid computational resources for use on a Grid computing system.

Essential Grid Workflow Monitoring Elements  

SciTech Connect

Troubleshooting Grid workflows is difficult. A typicalworkflow involves a large number of components networks, middleware,hosts, etc. that can fail. Even when monitoring data from all thesecomponents is accessible, it is hard to tell whether failures andanomalies in these components are related toa given workflow. For theGrid to be truly usable, much of this uncertainty must be elim- inated.We propose two new Grid monitoring elements, Grid workflow identifiersand consistent component lifecycle events, that will make Gridtroubleshooting easier, and thus make Grids more usable, by simplifyingthe correlation of Grid monitoring data with a particular Gridworkflow.

Enabling Campus Grids with Open Science Grid Technology  

NASA Astrophysics Data System (ADS)

The Open Science Grid is a recognized key component of the US national cyber-infrastructure enabling scientific discovery through advanced high throughput computing. The principles and techniques that underlie the Open Science Grid can also be applied to Campus Grids since many of the requirements are the same, even if the implementation technologies differ. We find five requirements for a campus grid: trust relationships, job submission, resource independence, accounting, and data management. The Holland Computing Center's campus grid at the University of Nebraska-Lincoln was designed to fulfill the requirements of a campus grid. A bridging daemon was designed to bring non-Condor clusters into a grid managed by Condor. Condor features which make it possible to bridge Condor sites into a multi-campus grid have been exploited at the Holland Computing Center as well.

Current Grid operation and future role of the Grid  

NASA Astrophysics Data System (ADS)

Grid-like technologies and approaches became an integral part of HEP experiments. Some other scientific communities also use similar technologies for data-intensive computations. The distinct feature of Grid computing is the ability to federate heterogeneous resources of different ownership into a seamless infrastructure, accessible via a single log-on. Like other infrastructures of similar nature, Grid functioning requires not only technologically sound basis, but also reliable operation procedures, monitoring and accounting. The two aspects, technological and operational, are closely related: weaker is the technology, more burden is on operations, and other way around. As of today, Grid technologies are still evolving: at CERN alone, every LHC experiment uses an own Grid-like system. This inevitably creates a heavy load on operations. Infrastructure maintenance, monitoring and incident response are done on several levels, from local system administrators to large international organisations, involving massive human effort worldwide. The necessity to commit substantial resources is one of the obstacles faced by smaller research communities when moving computing to the Grid. Moreover, most current Grid solutions were developed under significant influence of HEP use cases, and thus need additional effort to adapt them to other applications. Reluctance of many non-HEP researchers to use Grid negatively affects the outlook for national Grid organisations, which strive to provide multi-science services. We started from the situation where Grid organisations were fused with HEP laboratories and national HEP research programmes; we hope to move towards the world where Grid will ultimately reach the status of generic public computing and storage service provider and permanent national and international Grid infrastructures will be established. How far will we be able to advance along this path, depends on us. If no standardisation and convergence efforts will take place, Grid will become limited to HEP; if however the current multitude of Grid-like systems will converge to a generic, modular and extensible solution, Grid will become true to its name.

Privileged treatment of toddlers: cultural aspects of individual choice and responsibility.  

PubMed

This study examined the idea that toddlers in some communities are accorded a privileged status in which they are allowed what they want, assumed not yet to "understand" how to cooperate. U.S. middle-class and Guatemalan Mayan mothers and 3- to 5-year-old siblings were observed while the siblings and toddlers (14-20 months) both sought access to attractive objects. The Mayan toddlers' desires were usually respected by both the mothers and the siblings, who often voluntarily cooperated without mothers' intervention. In contrast, the U.S. middle-class toddlers seemed to be expected to follow the same rules for sharing (with some leniency) as the older children. The Mayan pattern fits a cultural model prioritizing both responsibility and respect for others' freedom of choice. PMID:14584984

Cloud Computing for the Grid: GridControl: A Software Platform to Support the Smart Grid  

SciTech Connect

GENI Project: Cornell University is creating a new software platform for grid operators called GridControl that will utilize cloud computing to more efficiently control the grid. In a cloud computing system, there are minimal hardware and software demands on users. The user can tap into a network of computers that is housed elsewhere (the cloud) and the network runs computer applications for the user. The user only needs interface software to access all of the cloud’s data resources, which can be as simple as a web browser. Cloud computing can reduce costs, facilitate innovation through sharing, empower users, and improve the overall reliability of a dispersed system. Cornell’s GridControl will focus on 4 elements: delivering the state of the grid to users quickly and reliably; building networked, scalable grid-control software; tailoring services to emerging smart grid uses; and simulating smart grid behavior under various conditions.

Power Grid Issues  

NSDL National Science Digital Library

Tampa Electric (1) offers animated illustrations that show how electricity is created and distributed. The first lets the user see the main components of a power plant, while the second outlines what is involved in transmission from the power plant to the destination. A less flashy but more detailed description of the electricity generation process is provided by the Energy Information Administration (2). This site goes more into different generation methods, such as coal, nuclear, and solar power. A few Energy Information Sheets and other resources are also available. Fuel cells are commonly discussed in terms of alternative fuel vehicles, but they might find their way into the power grid before they become standard in cars. This possibility is explored in an eight-page article (3) that highlights examples of hydrogen-powered energy systems. A similar topic is addressed in a February 2003 article in Popular Science (4). However, instead of dealing with large-scale fuel cell power plants, the article introduces fuel cells that can produce enough energy for a single family. Equipping every home with such a cell could make transmission lines obsolete, but the fact that this is currently infeasible is acknowledged. A research paper from Washington State University (5) identifies a number of risks to the power grid that could be exploited by terrorists. The authors propose specific research areas on which to focus in order to mitigate these risks, mainly dealing with communications and grid control. Related to this paper is an April 2003 article describing security measures that are being implemented to strengthen the computer systems used to operate generators and other grid components (6). The additional measures were necessary because of known weaknesses that made the systems vulnerable to intrusions. Since coal is one of the cheapest and widely available natural resources, Los Alamos National Laboratory is researching ways to make coal burning generators cleaner. The Clean Coal Technology project began several years ago, and this is one of several reports discussing a particular aspect of the project (7). The Integrated Energy and Communications System Architecture (8) is an initiative to combine the development of the power grid with advanced distributed computing technologies. The goal is to create a more efficient grid with capabilities of self-healing and intelligent management. An overview of the initiative is given on its Web site, as well as a more detailed white paper.

Data Qulaification Report: Topographic Grid  

SciTech Connect

The data set considered here is the topographic grid used in the Geologic Framework Model (GFM). The grid has been used in each version of the GFM, and was extracted from GFM3.1 (M09901MWDGFM3 1.000, file name ''topography.2grd''). The grid was given a unique DTN (M00002SPATOP00.001). A Technical Assessment method was used to evaluate these data to determine the adequacy of the grid for use in three-dimensional modeling. The topographic grid was compared to qualified borehole collar survey data (DTN: M09906GPS98410.000) and the mismatches documented. An acceptance window was established for the topographic grid based on the needs of the data users. The grid was determined to be within the acceptance window, and was determined to be adequate for its intended use in three-dimensional spatial modeling and is recommended to be Qualified.

Artifacts produced by moving grids.  

PubMed

Anti-scatter grids reduce the amount of secondary radiation contributing to the image and improve the signal-to-noise ratio. However, they may also lead to the creation of linear artifacts representing the shadows of the radiopaque septa. Grid motion perpendicular to the septa during the exposure can cause blurring of the artifacts; however, the wider septa of recently proposed grids increase the difficulty of suppressing the artifacts entirely. Physical characteristics which affect perceptibility of grid-line artifacts and the conditions needed for their elimination are analyzed. Sufficient grid movement can eliminate overlap artifacts, while synchronization of linear grid motion with exposure time can suppress artifacts for relatively small grid movements. PMID:6828740

3D Structured Grid Adaptation  

NASA Technical Reports Server (NTRS)

Grid adaptation for structured meshes is the art of using information from an existing, but poorly resolved, solution to automatically redistribute the grid points in such a way as to improve the resolution in regions of high error, and thus the quality of the solution. This involves: (1) generate a grid vis some standard algorithm, (2) calculate a solution on this grid, (3) adapt the grid to this solution, (4) recalculate the solution on this adapted grid, and (5) repeat steps 3 and 4 to satisfaction. Steps 3 and 4 can be repeated until some 'optimal' grid is converged to but typically this is not worth the effort and just two or three repeat calculations are necessary. They also may be repeated every 5-10 time steps for unsteady calculations.

Progress in Grid Generation: From Chimera to DRAGON Grids  

NASA Technical Reports Server (NTRS)

Hybrid grids, composed of structured and unstructured grids, combines the best features of both. The chimera method is a major stepstone toward a hybrid grid from which the present approach is evolved. The chimera grid composes a set of overlapped structured grids which are independently generated and body-fitted, yielding a high quality grid readily accessible for efficient solution schemes. The chimera method has been shown to be efficient to generate a grid about complex geometries and has been demonstrated to deliver accurate aerodynamic prediction of complex flows. While its geometrical flexibility is attractive, interpolation of data in the overlapped regions - which in today's practice in 3D is done in a nonconservative fashion, is not. In the present paper we propose a hybrid grid scheme that maximizes the advantages of the chimera scheme and adapts the strengths of the unstructured grid while at the same time keeps its weaknesses minimal. Like the chimera method, we first divide up the physical domain by a set of structured body-fitted grids which are separately generated and overlaid throughout a complex configuration. To eliminate any pure data manipulation which does not necessarily follow governing equations, we use non-structured grids only to directly replace the region of the arbitrarily overlapped grids. This new adaptation to the chimera thinking is coined the DRAGON grid. The nonstructured grid region sandwiched between the structured grids is limited in size, resulting in only a small increase in memory and computational effort. The DRAGON method has three important advantages: (1) preserving strengths of the chimera grid; (2) eliminating difficulties sometimes encountered in the chimera scheme, such as the orphan points and bad quality of interpolation stencils; and (3) making grid communication in a fully conservative and consistent manner insofar as the governing equations are concerned. To demonstrate its use, the governing equations are discretized using the newly proposed flux scheme, AUSM+, which will be briefly described herein. Numerical tests on representative 2D inviscid flows are given for demonstration. Finally, extension to 3D is underway, only paced by the availability of the 3D unstructured grid generator.

Gridded electron reversal ionizer  

NASA Technical Reports Server (NTRS)

A gridded electron reversal ionizer forms a three dimensional cloud of zero or near-zero energy electrons in a cavity within a filament structure surrounding a central electrode having holes through which the sample gas, at reduced pressure, enters an elongated reversal volume. The resultant negative ion stream is applied to a mass analyzer. The reduced electron and ion space-charge limitations of this configuration enhances detection sensitivity for material to be detected by electron attachment, such as narcotic and explosive vapors. Positive ions may be generated by generating electrons having a higher energy, sufficient to ionize the target gas and pulsing the grid negative to stop the electron flow and pulsing the extraction aperture positive to draw out the positive ions.

TRMM Gridded Text Products  

NASA Technical Reports Server (NTRS)

NASA's Tropical Rainfall Measuring Mission (TRMM) has many products that contain instantaneous or gridded rain rates often among many other parameters. However, these products because of their completeness can often seem intimidating to users just desiring surface rain rates. For example one of the gridded monthly products contains well over 200 parameters. It is clear that if only rain rates are desired, this many parameters might prove intimidating. In addition, for many good reasons these products are archived and currently distributed in HDF format. This also can be an inhibiting factor in using TRMM rain rates. To provide a simple format and isolate just the rain rates from the many other parameters, the TRMM product created a series of gridded products in ASCII text format. This paper describes the various text rain rate products produced. It provides detailed information about parameters and how they are calculated. It also gives detailed format information. These products are used in a number of applications with the TRMM processing system. The products are produced from the swath instantaneous rain rates and contain information from the three major TRMM instruments: radar, radiometer, and combined. They are simple to use, human readable, and small for downloading.

The Volume Grid Manipulator (VGM): A Grid Reusability Tool  

NASA Technical Reports Server (NTRS)

This document is a manual describing how to use the Volume Grid Manipulation (VGM) software. The code is specifically designed to alter or manipulate existing surface and volume structured grids to improve grid quality through the reduction of grid line skewness, removal of negative volumes, and adaption of surface and volume grids to flow field gradients. The software uses a command language to perform all manipulations thereby offering the capability of executing multiple manipulations on a single grid during an execution of the code. The command language can be input to the VGM code by a UNIX style redirected file, or interactively while the code is executing. The manual consists of 14 sections. The first is an introduction to grid manipulation; where it is most applicable and where the strengths of such software can be utilized. The next two sections describe the memory management and the manipulation command language. The following 8 sections describe simple and complex manipulations that can be used in conjunction with one another to smooth, adapt, and reuse existing grids for various computations. These are accompanied by a tutorial section that describes how to use the commands and manipulations to solve actual grid generation problems. The last two sections are a command reference guide and trouble shooting sections to aid in the use of the code as well as describe problems associated with generated scripts for manipulation control.

Stem cell therapies for intervertebral disc degeneration: immune privilege reinforcement by Fas/FasL regulating machinery.  

PubMed

As a main contributing factor to low back pain, intervertebral disc degeneration (IDD) is the fundamental basis for various debilitating spinal diseases. The pros and cons of current treatment modalities necessitate biological treatment strategies targeting for reversing or altering the degeneration process in terms of molecules or genes. The advances in stem cell research facilitate the studies aiming for possible clinical application of stem cell therapies for IDD. Human NP cells are versatile with cell morphology full of variety, capable of synthesizing extracellular matrix components, engulfing substances by autophagy and phagocytosis, mitochondrial vacuolization indicating dysfunction, expressing Fas and FasL as significant omens of immune privileged sites. Human discs belong to immune privilege organs with functional FasL expression, which can interact with invasive immune cells by Fas-FasL regulatory machinery. IDD is characterized by decreased expression level of FasL with dysfunctional FasL, which in turn unbalances the interaction between NP cells and immune cells. Certain modulation factors might play a role in the process, such as miR-155. Accumulating evidence indicates that Fas-FasL network expresses in a variety of stem cells. Given the expression of functional FasL and insensitive Fas in stem cells (we term as FasL privilege), transplantation of stem cells into the disc may regenerate the degenerative disc by not only differentiating into NP-like cells, increasing extracellular matrix, but also reinforce immune privilege via interaction with immune cells by Fas-FasL network.

Nonsuicidal Self-Injury Among “Privileged” Youths: Longitudinal and Cross-Sectional Approaches to Developmental Process  

PubMed Central

This investigation examined process-level pathways to nonsuicidal self-injury (NSSI; e.g., self-cutting, -burning, -hitting) in 2 cohorts of suburban, upper-middle-class youths: a cross-sectional sample of 9th–12th graders (n = 1,036, 51.9% girls) on the West Coast and a longitudinal sample followed annually from the 6th through 12th grades (n = 245, 53.1% girls) on the East Coast. High rates of NSSI were found in both the cross-sectional (37.2%) and the longitudinal (26.1%) samples. Zero-inflated Poisson regression models estimated process-level pathways from perceived parental criticism to NSSI via youth-reported alienation toward parents. Pathways toward the initiation of NSSI were distinct from those accounting for its frequency. Parental criticism was associated with increased NSSI, and youth alienation toward parents emerged as a relevant process underlying this pathway, particularly for boys. The specificity of these pathways was explored by examining separate trajectories toward delinquent outcomes. The findings illustrate the prominence of NSSI among “privileged” youths, the salience of the caregiving environment in NSSI, the importance of parental alienation in explaining these relations, and the value of incorporating multiple systems in treatment approaches for adolescents who self-injure.

[Neurosciences and the ravings of the Soviet era. Spanish Republican physicians, a set of privileged witnesses].  

PubMed

This study analyses the links between the Russian and Soviet neurosciences and their Spanish counterpart, especially with regard to the experiences of the Spanish Republican physicians exiled in the USSR. The Russian neurosciences, which date back to the second half of the 19th century, followed a path that ran parallel to the discipline throughout the rest of Europe and finally displayed signs of being influenced by the German and French schools. Important figures include Alexei Kojevnikov and Vladimir Bekhterev in neurology, Sergei Korsakov in psychiatry, Ivan Pavlov and his disciple Piotr Anojin in neurophysiology, Lev Vygotsky and Alexander Luria in neuropsychology, and Nikolai Burdenko in neurosurgery. When the Bolsheviks came to power, they brought with them a progressive conception of health care, which was modified during the Stalinist era to serve political interests, above all in the case of psychiatry. During the first third of the 20th century, Spanish scientists became interested in Pavlov's reflexology and the Soviets took a similar interest in Spanish histology. Among the 4500 Spanish Republicans who emigrated to the USSR because of the Spanish Civil War, there were several dozen physicians who were privileged witnesses of the madness that shook the science and the health care of that period. Relevant names worth citing here from the field of the neurosciences include Juan Planelles and Ramon Alvarez-Buylla in neurophysiology, Federico Pascual and Florencio Villa Landa in psychiatry, Angel Escobio and Maria Perez in neurology, Julian Fuster in neurosurgery and Manuel Arce in neuroimaging.

Effects of calcitonin gene-related peptide on the immune privilege of human hair follicles.  

PubMed

The hair follicle is a widely available and instructive miniature organ in the human body that experiences major histocompatibility complex (MHC) class I dependent immune privilege (IP). There are various regulation factors that act on the generation, maintenance, and collapse of hair follicle IP. Neuropeptides such as calcitonin gene-related peptide (CGRP) are created in many organs, including skin, and display various immune regulation effects. The purpose of this study was to investigate the phenotypic effect of CGRP on the hair follicle's IP. First, we used interferon-? (IFN-?) to generate ectopic MHC antigen expression model in cultured human hair follicles as previously described. Then, we examined the effects of CGRP on the regulation of ectopic MHC antigen expression in cultured human hair follicles using reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemical staining techniques. IFN-? (75 IU/ml) induced ectopic MHC expression. CGRP down-regulated INF-?-induced ectopic MHC class I mRNA expression. These down-regulated effects were especially evident in 10(-8)M. In addition, CGRP also suppressed the staining intensity related to the expression of MHC class I and MHC class I-pathway related molecules (?2-microglobulin), but had no effect on MHC class II antigen expression. Taken together, these results indicate that CGRP might be an important regulatory factor for IP maintenance and restoration of IP via suppression of MHC class I antigen. PMID:22975462

Explaining and inducing savant skills: privileged access to lower level, less-processed information  

PubMed Central

I argue that savant skills are latent in us all. My hypothesis is that savants have privileged access to lower level, less-processed information, before it is packaged into holistic concepts and meaningful labels. Owing to a failure in top-down inhibition, they can tap into information that exists in all of our brains, but is normally beyond conscious awareness. This suggests why savant skills might arise spontaneously in otherwise normal people, and why such skills might be artificially induced by low-frequency repetitive transcranial magnetic stimulation. It also suggests why autistic savants are atypically literal with a tendency to concentrate more on the parts than on the whole and why this offers advantages for particular classes of problem solving, such as those that necessitate breaking cognitive mindsets. A strategy of building from the parts to the whole could form the basis for the so-called autistic genius. Unlike the healthy mind, which has inbuilt expectations of the world (internal order), the autistic mind must simplify the world by adopting strict routines (external order). PMID:19528023

Privilege, power, and public health programs: a student perspective on deconstructing institutional racism in community service learning.  

PubMed

The Association of Schools of Public Health has identified "diversity and culture" as 1 of 7 crosscutting competencies that public health students are expected to achieve. This competency is traditionally incorporated into the curriculum through a community service-learning (CSL) component that aims to expose students to racial/ethnic health disparities. However, this model of CSL is problematic because although students are directly engaging with community members, it does not ensure long-term sustainable changes or benefits for the host community. Moreover, academic institutions have developed significant critiques of traditional CSL models where white middle-class students engage with low-income clients and communities of color, potentially reinforcing Eurocentric power and privilege. As such, public health programs require a shift in both pedagogy and curricula that more directly addresses underlying institutional racism in health disparities. Consistent with the principles of public health, a social justice framework is imperative in teaching cultural competency and should facilitate discussion of racial injustice and privilege in the students' own lives. This brief presents an autobiographical personal narrative of my experiences with CSL as a racial/ethnic minority student in a California graduate school of public health. Although autoethnography is inherently limited, this brief highlights my observations of the limitations of the service-learning model to adequately educate students on the intersection of racism and health outcomes. In addition, the brief includes suggestions for creating inclusive curricula that critically examine issues of privilege, oppression, and power dynamics related to race/ethnicity. PMID:21617417

Grid Generation Techniques Utilizing the Volume Grid Manipulator  

NASA Technical Reports Server (NTRS)

This paper presents grid generation techniques available in the Volume Grid Manipulation (VGM) code. The VGM code is designed to manipulate existing line, surface and volume grids to improve the quality of the data. It embodies an easy to read rich language of commands that enables such alterations as topology changes, grid adaption and smoothing. Additionally, the VGM code can be used to construct simplified straight lines, splines, and conic sections which are common curves used in the generation and manipulation of points, lines, surfaces and volumes (i.e., grid data). These simple geometric curves are essential in the construction of domain discretizations for computational fluid dynamic simulations. By comparison to previously established methods of generating these curves interactively, the VGM code provides control of slope continuity and grid point-to-point stretchings as well as quick changes in the controlling parameters. The VGM code offers the capability to couple the generation of these geometries with an extensive manipulation methodology in a scripting language. The scripting language allows parametric studies of a vehicle geometry to be efficiently performed to evaluate favorable trends in the design process. As examples of the powerful capabilities of the VGM code, a wake flow field domain will be appended to an existing X33 Venturestar volume grid; negative volumes resulting from grid expansions to enable flow field capture on a simple geometry, will be corrected; and geometrical changes to a vehicle component of the X33 Venturestar will be shown.

LDCM Grid Prototype (LGP)  

NASA Technical Reports Server (NTRS)

The LGP successfully demonstrated that grid technology could be used to create a collaboration among research scientists, their science development machines, and distributed data to create a science production system in a nationally distributed environment. Grid technology provides a low cost and effective method of enabling production of science products by the science community. To demonstrate this, the LGP partnered with NASA GSFC scientists and used their existing science algorithms to generate virtual Landsat-like data products using distributed data resources. LGP created 48 output composite scenes with 4 input scenes each for a total of 192 scienes processed in parallel. The demonstration took 12 hours, which beat the requirement by almost 50 percent, well within the LDCM requirement to process 250 scenes per day. The LGP project also showed the successful use of workflow tools to automate the processing. Investing in this technology has led to funding for a ROSES ACCESS proposal. The proposal intends to enable an expert science user to produce products from a number of similar distributed instrument data sets using the Land Cover Change Community-based Processing and Analysis System (LC-ComPS) Toolbox. The LC-ComPS Toolbox is a collection of science algorithms that enable the generation of data with ground resolution on the order of Landsat-class instruments.

Grid-Enabled Measures  

PubMed Central

Scientists are taking advantage of the Internet and collaborative web technology to accelerate discovery in a massively connected, participative environment —a phenomenon referred to by some as Science 2.0. As a new way of doing science, this phenomenon has the potential to push science forward in a more efficient manner than was previously possible. The Grid-Enabled Measures (GEM) database has been conceptualized as an instantiation of Science 2.0 principles by the National Cancer Institute with two overarching goals: (1) Promote the use of standardized measures, which are tied to theoretically based constructs; and (2) Facilitate the ability to share harmonized data resulting from the use of standardized measures. This is done by creating an online venue connected to the Cancer Biomedical Informatics Grid (caBIG®) where a virtual community of researchers can collaborate together and come to consensus on measures by rating, commenting and viewing meta-data about the measures and associated constructs. This paper will describe the web 2.0 principles on which the GEM database is based, describe its functionality, and discuss some of the important issues involved with creating the GEM database, such as the role of mutually agreed-on ontologies (i.e., knowledge categories and the relationships among these categories— for data sharing).

LAPS Grid generation and adaptation  

NASA Astrophysics Data System (ADS)

LAPS uses a common-data framework in which a general purpose grid generation and adaptation package in toroidal and simply connected domains is implemented. The initial focus is on implementing the Winslow/Laplace-Beltrami method for generating non-overlapping block structured grids. This is to be followed by a grid adaptation scheme based on Monge-Kantorovich optimal transport method [Delzanno et al., J. Comput. Phys,227 (2008), 9841-9864], that equidistributes application-specified error. As an initial set of applications, we will lay out grids for an axisymmetric mirror, a field reversed configuration, and an entire poloidal cross section of a tokamak plasma reconstructed from a CMOD experimental shot. These grids will then be used for computing the plasma equilibrium and transport in accompanying presentations. A key issue for Monge-Kantorovich grid optimization is the choice of error or monitor function for equi-distribution. We will compare the Operator Recovery Error Source Detector (ORESD) [Lapenta, Int. J. Num. Meth. Eng,59 (2004) 2065-2087], the Tau method and a strategy based on the grid coarsening [Zhang et al., AIAA J,39 (2001) 1706-1715] to find an ``optimal'' grid.

Intelligent automated surface grid generation  

NASA Technical Reports Server (NTRS)

The goal of our research is to produce a flexible, general grid generator for automated use by other programs, such as numerical optimizers. The current trend in the gridding field is toward interactive gridding. Interactive gridding more readily taps into the spatial reasoning abilities of the human user through the use of a graphical interface with a mouse. However, a sometimes fruitful approach to generating new designs is to apply an optimizer with shape modification operators to improve an initial design. In order for this approach to be useful, the optimizer must be able to automatically grid and evaluate the candidate designs. This paper describes and intelligent gridder that is capable of analyzing the topology of the spatial domain and predicting approximate physical behaviors based on the geometry of the spatial domain to automatically generate grids for computational fluid dynamics simulators. Typically gridding programs are given a partitioning of the spatial domain to assist the gridder. Our gridder is capable of performing this partitioning. This enables the gridder to automatically grid spatial domains of wide range of configurations.

TIGER: Turbomachinery interactive grid generation  

NASA Technical Reports Server (NTRS)

A three dimensional, interactive grid generation code, TIGER, is being developed for analysis of flows around ducted or unducted propellers. TIGER is a customized grid generator that combines new technology with methods from general grid generation codes. The code generates multiple block, structured grids around multiple blade rows with a hub and shroud for either C grid or H grid topologies. The code is intended for use with a Euler/Navier-Stokes solver also being developed, but is general enough for use with other flow solvers. TIGER features a silicon graphics interactive graphics environment that displays a pop-up window, graphics window, and text window. The geometry is read as a discrete set of points with options for several industrial standard formats and NASA standard formats. Various splines are available for defining the surface geometries. Grid generation is done either interactively or through a batch mode operation using history files from a previously generated grid. The batch mode operation can be done either with a graphical display of the interactive session or with no graphics so that the code can be run on another computer system. Run time can be significantly reduced by running on a Cray-YMP.

Skew grids and irrotational flow  

NASA Astrophysics Data System (ADS)

Finite-difference computation of incompressible flow through regions of arbitrary shape often requires the implementation of boundary-fitted coordinates for which the grid lines may be non-orthogonal (skew). When the governing equations are expressed in terms of pressure and velocity, conservation of mass is maintained by the gradient of the pressure. In principle, the gradient is irrotational and should have no effect on the existing circulation in the flow field; but if the grid lines are skew, the discrete representation of the gradient can generate spurious vorticity near the boundaries. In the present work this difficulty is eliminated for uniform skew grids, and markedly reduced for non-uniform skew grids, by adopting a discrete formulation of the pressure gradient that helps maintain irrotationality near boundaries. The procedure is applicable for staggered grids with either Poisson or Chorin equations for pressure.

Lichen planopilaris is characterized by immune privilege collapse of the hair follicle's epithelial stem cell niche.  

PubMed

Lichen planopilaris (LPP) is a chronic inflammatory disease of unknown pathogenesis that leads to permanent hair loss. Whilst destruction of epithelial hair follicle stem cells (eHFSCs) that reside in an immunologically protected niche of the HF epithelium, the bulge, is a likely key event in LPP pathogenesis, this remains to be demonstrated. We have tested the hypotheses that bulge immune privilege (IP) collapse and inflammation-induced eHFSC death are key components in the pathogenesis of LPP. Biopsies of lesional and non-lesional scalp skin from adult LPP patients (n = 42) were analysed by quantitative (immuno)histomorphometry, real-time quantitative polymerase chain reaction (qRT-PCR), laser capture microdissection and microarray analysis, or skin organ culture. At both the protein and transcriptional level, lesional LPP HFs showed evidence for bulge IP collapse (ie increased expression of MHC class I and II, ?2microglobulin; reduced TGF?2 and CD200 expression). This was accompanied by a Th1-biased cytotoxic T cell response (ie increased CD8(+) GranzymeB(+) T cells and CD123(+) plasmacytoid dendritic cells, with increased CXCR3 expression) and increased expression of interferon-inducible chemokines (CXCL9/10/11). Interestingly, lesional LPP eHFSCs showed both increased proliferation and apoptosis in situ. Microarray analysis revealed a loss of eHFSC signatures and increased expression of T cell activation/binding markers in active LPP, while bulge PPAR? transcription was unaltered compared to non-lesional LPP HFs. In organ culture of non-lesional LPP skin, interferon-? (IFN?) induced bulge IP collapse. LPP is an excellent model disease for studying and preventing immune destruction of human epithelial stem cells in situ. These novel findings raise the possibility that LPP represents an autoimmune disease in whose pathogenesis IFN?-induced bulge IP collapse plays an important role. Therapeutically, bulge IP protection/restoration may help to better manage this highly treatment-resistant cicatricial alopecia. PMID:23788005

Mouse brain: an immunologically privileged site for natural resistance against lymphoma cells  

SciTech Connect

The present study deals with classical graft response and natural resistance against lymphoma cells in mouse brain, evaluated in terms of either survival times or extent of lymphoma cell proliferation measured by the percentage of /sup 125/lUdR uptake. The results show the following: a) CGR was easily detected in the brain of allogeneic nonirradiated recipients by using either parameter. CGR was easily abrogated by total-body irradiation and was absent in ''nude'' recipients when tested by the /sup 125/lUdR uptake technique. b) No difference in the growth patterns of H-2/sup b/ lymphoma cells was detected in the brain of irradiated histocompatible or Hh-incompatible hybrid (H-2/sup b/ / H-2/sup d/) or allogeneic (H-2/sup b/, H-2/sup i//sup 5/) mice or Hh-compatible H-2/sup h//sup 2/ hosts inoculated intracerebrally (i.c.) with the tumor. On the contrary, strong resistance to lymphoma graft was confirmed in the spleen of irradiated Hh-incompatible recipients inoculated i.v. with the tumor. c) No impairment of splenic resistance against lymphoma cells was afforded by the simultaneous administration of the same tumor into the brain, thus ruling out the possibility that the i.c. challenge with lymphoma cells abrogated NR of the host. d) Mortality studies in nonirradiated Hh-incompatible hybrid or nude mice suggested that only marginal NR could be detected in mouse brain. These data suggest that mouse brain can be considered an ''immunologically privileged'' site for NR more than for CGR, and provide the immunologic bases for explaining the successful take of xenogeneic lymphoid tumors in the brain of nude mice.

A Java commodity grid kit.  

SciTech Connect

In this paper we report on the features of the Java Commodity Grid Kit. The Java CoG Kit provides middleware for accessing Grid functionality from the Java framework. Java CoG Kit middleware is general enough to design a variety of advanced Grid applications with quite different user requirements. Access to the Grid is established via Globus protocols, allowing the Java CoG Kit to communicate also with the C Globus reference implementation. Thus, the Java CoG Kit provides Grid developers with the ability to utilize the Grid, as well as numerous additional libraries and frameworks developed by the Java community to enable network, Internet, enterprise, and peer-to peer computing. A variety of projects have successfully used the client libraries of the Java CoG Kit to access Grids driven by the C Globus software. In this paper we also report on the efforts to develop server side Java CoG Kit components. As part of this research we have implemented a prototype pure Java resource management system that enables one to run Globus jobs on platforms on which a Java virtual machine is supported, including Windows NT machines.

Grid spacing control with variation diminishing splines  

NASA Technical Reports Server (NTRS)

Methods used to specify and control two and three dimensional grids on which numerical solutions of partial differential equations may be obtained were studied. While initially focusing on grid generation, the research will evolve into a consideration of the interaction of grid generation with the solution of a partial differential equation. The multisurface method of grid generation was used to continuously patch a grid onto an existing grid. In the resulting grid the elements of the Jacobian matrix must be continuous across the boundary between the original grid and the patched grid. Programs were written which accept as input the coordinates of the original grid and the desired new boundary, and then use the three-surface or four-surface version of the multisurface method to extend the original grid out to a new boundary.

National Smart Water Grid  

SciTech Connect

The United States repeatedly experiences floods along the Midwest's large rivers and droughts in the arid Western States that cause traumatic environmental conditions with huge economic impact. With an integrated approach and solution these problems can be alleviated. Tapping into the Mississippi River and its tributaries, the world's third largest fresh water river system, during flood events will mitigate the damage of flooding and provide a new source of fresh water to the Western States. The trend of increased flooding on the Midwest's large rivers is supported by a growing body of scientific literature. The Colorado River Basin and the western states are experiencing a protracted multi-year drought. Fresh water can be pumped via pipelines from areas of overabundance/flood to areas of drought or high demand. Calculations document 10 to 60 million acre-feet (maf) of fresh water per flood event can be captured from the Midwest's Rivers and pumped via pipelines to the Colorado River and introduced upstream of Lake Powell, Utah, to destinations near Denver, Colorado, and used in areas along the pipelines. Water users of the Colorado River include the cities in southern Nevada, southern California, northern Arizona, Colorado, Utah, Indian Tribes, and Mexico. The proposed start and end points, and routes of the pipelines are documented, including information on right-of-ways necessary for state and federal permits. A National Smart Water Grid{trademark} (NSWG) Project will create thousands of new jobs for construction, operation, and maintenance and save billions in drought and flood damage reparations tax dollars. The socio-economic benefits of NWSG include decreased flooding in the Midwest; increased agriculture, and recreation and tourism; improved national security, transportation, and fishery and wildlife habitats; mitigated regional climate change and global warming such as increased carbon capture; decreased salinity in Colorado River water crossing the US-Mexico border; and decreased eutrophication (excessive plant growth and decay) in the Gulf of Mexico to name a few. The National Smart Water Grid{trademark} will pay for itself in a single major flood event.

GridWise: Transforming the Power Grid with Information Technology  

SciTech Connect

GridWise™ is a vision for the future electric system shared by a new DOE initiative and an industry alliance. GridWise is built upon the fundamental premise that information technology will profoundly transform the plan¬ning and operation of the power grid, just at is has changed business, education, and entertainment. The electric power system has served us remarkably well for over half a century. However, with business-as-usual solutions, the U.S. will invest around $450 billion in conventional electric infrastructure—generation, transmission, and distribution—over the next 20 years just to meet demand for a growing population and economy. Even more investment will be needed to relieve the growing backlog of deferred transmission additions. Since the mortgage on infrastructure is a major component of electric rates, economic prosperity and our way of life depend upon minimizing the need for new infrastructure by increasing the utilization of these assets. This paper discusses the GridWise vision and describes some example technologies and how they are woven together to fundamentally alter the way the power grid works. The benefits of an information-rich power system and key elements of the DOE’s new GridWise initiative are also presented.

Symbolic Constraint Maintenance Grid  

NASA Technical Reports Server (NTRS)

Version 3.1 of Symbolic Constraint Maintenance Grid (SCMG) is a software system that provides a general conceptual framework for utilizing pre-existing programming techniques to perform symbolic transformations of data. SCMG also provides a language (and an associated communication method and protocol) for representing constraints on the original non-symbolic data. SCMG provides a facility for exchanging information between numeric and symbolic components without knowing the details of the components themselves. In essence, it integrates symbolic software tools (for diagnosis, prognosis, and planning) with non-artificial-intelligence software. SCMG executes a process of symbolic summarization and monitoring of continuous time series data that are being abstractly represented as symbolic templates of information exchange. This summarization process enables such symbolic- reasoning computing systems as artificial- intelligence planning systems to evaluate the significance and effects of channels of data more efficiently than would otherwise be possible. As a result of the increased efficiency in representation, reasoning software can monitor more channels and is thus able to perform monitoring and control functions more effectively.

Grid Visualization Tool  

NASA Technical Reports Server (NTRS)

The Grid Visualization Tool (GVT) is a computer program for displaying the path of a mobile robotic explorer (rover) on a terrain map. The GVT reads a map-data file in either portable graymap (PGM) or portable pixmap (PPM) format, representing a gray-scale or color map image, respectively. The GVT also accepts input from path-planning and activity-planning software. From these inputs, the GVT generates a map overlaid with one or more rover path(s), waypoints, locations of targets to be explored, and/or target-status information (indicating success or failure in exploring each target). The display can also indicate different types of paths or path segments, such as the path actually traveled versus a planned path or the path traveled to the present position versus planned future movement along a path. The program provides for updating of the display in real time to facilitate visualization of progress. The size of the display and the map scale can be changed as desired by the user. The GVT was written in the C++ language using the Open Graphics Library (OpenGL) software. It has been compiled for both Sun Solaris and Linux operating systems.

Practice-centred evaluation and the privileging of care in health information technology evaluation  

PubMed Central

Background Electronic Patient Records (EPRs) and telemedicine are positioned by policymakers as health information technologies that are integral to achieving improved clinical outcomes and efficiency savings. However, evaluating the extent to which these aims are met poses distinct evaluation challenges, particularly where clinical and cost outcomes form the sole focus of evaluation design. We propose that a practice-centred approach to evaluation - in which those whose day-to-day care practice is altered (or not) by the introduction of new technologies are placed at the centre of evaluation efforts – can complement and in some instances offer advantages over, outcome-centric evaluation models. Methods We carried out a regional programme of innovation in renal services where a participative approach was taken to the introduction of new technologies, including: a regional EPR system and a system to support video clinics. An ‘action learning’ approach was taken to procurement, pre-implementation planning, implementation, ongoing development and evaluation. Participants included clinicians, technology specialists, patients and external academic researchers. Whilst undergoing these activities we asked: how can a practice-centred approach be embedded into evaluation of health information technologies? Discussion Organising EPR and telemedicine evaluation around predetermined outcome measures alone can be impractical given the complex and contingent nature of such projects. It also limits the extent to which unforeseen outcomes and new capabilities are recognised. Such evaluations often fail to improve understanding of ‘when’ and ‘under what conditions’ technology-enabled service improvements are realised, and crucially, how such innovation improves care. Summary Our contribution, drawn from our experience of the case study provided, is a protocol for practice-centred, participative evaluation of technology in the clinical setting that privileges care. In this context ‘practice-centred’ evaluation acts as a scalable, coordinating framework for evaluation that recognises health information technology supported care as an achievement that is contingent and ongoing. We argue that if complex programmes of technology-enabled service innovation are understood in terms of their contribution to patient care and supported by participative, capability-building evaluation methodologies, conditions are created for practitioners and patients to realise the potential of technologies and make substantive contributions to the evidence base underpinning health innovation programmes.

Grid cells on the ball  

NASA Astrophysics Data System (ADS)

What sort of grid cells do we expect to see in rodents who have spent their developmental period inside a large spherical cage? Or, in a different experimental paradigm, toddling on a revolving ball, with virtual reality simulating a coherently revolving surround? We consider a simple model of grid firing map formation, based on firing rate adaptation, that we have earlier analyzed when playing out on a flat environment. The model predicts that whether experienced on the outside or inside, a spherical environment induces one of a succession of grid maps realized as combinations of spherical harmonics, depending on the relation of the radius to the preferred grid spacing, itself related to the parameters of firing rate adaptation. Numerical simulations concur with analytical predictions.

Astrophysics in the EGEE Grid  

NASA Astrophysics Data System (ADS)

EGEE, the most important European Grid Infrastructure funded by the EU Commission, is now in the process of submitting a proposal within the EU 7th Framework Programme to start the third phase (EGEE-III) of the project. The Astronomy and Astrophysics (A&A) Community has proven to be particularly attractive for EGEE, since its typical applications are considered strategic, i.e. challenging enough to be chosen as good validators of the EGEE Grid infrastructure. Conversely, a ``call for astrophysical applications'' launched in the past months gathered many responses from groups of astronomers interested in contributing applications to be gridified. This positive answer is a further demonstration that the community of astronomers who look at the Grid as the right technology for many aspects of their everyday work is rapidly growing. In the 2008-2009 framework, the plan is to support the gridification of selected astrophysical applications using EU funds. In the meantime, a consistent development activity on the Grid middleware is being carried out by a number of research groups of the A&A Community. The goal is to enhance the capabilities of the current Grids to make them able to fully meet the requirements of typical A&A applications and also of other disciplines, and to bridge the Grid and the Virtual Observatory. Both EGEE and the A&A Community, therefore, can mutually benefit of a stronger synergy.

Ion beamlet vectoring by grid translation  

NASA Technical Reports Server (NTRS)

Ion beamlet vectoring is investigated by collecting deflection and divergence angle data for two-grid systems as a function of the relative displacement of these grids. Results show that at large displacements, accelerator grid impingement becomes a limiting factor and this determines the useful range of beamlet deflection. Beamlet deflection was shown to vary linearly with grid offset angle over this range. Values of deflection-to-offset angle ratio and useful range of deflection are presented as functions of grid-hole geometries, perveance levels, and accelerating voltages. It is found that the divergence of the beamlets is unaffected by deflection over the useful range of beamlet deflection. The grids of a typical dished-grid ion thruster are examined to determine where over the grid surface the grid offsets exceed the useful range, which indicates the regions on the surface where high accelerator grid impingment is probably occurring.

Does the granting of legal privileges as an indigenous people help to reduce health disparities? Evidence from New Zealand and Malaysia.  

PubMed

Both the Maori of New Zealand and the Orang Asli of Malaysia are indigenous peoples who have been subjected to prejudice, discrimination and displacement in its various forms by other ethnic groups in their respective countries. However, owing to changes in the socio-political climate, they have been granted rights (including legal privileges) in more recent times. Data pertaining to the health and socio-economic status of the Maori and the Orang Asli are analysed to see if the granting of legal privileges has made any difference for the two communities. One conclusion is that legal privileges (and the granting of special status) do not appear to work well in terms of reducing health and socio-economic gaps. PMID:20443525

Europe and ESTRO moving East. A story of betrayal and redemption—Candid observations by a privileged witness  

PubMed Central

After briefly looking into the dramatic twist of history that caused Central- and Eastern Europe to be separated from the West, the author observes the impact of 40 years of cold war and isolation on the state of radiotherapy (RT) in Central Europe. From her privileged position as a staff member in charge of public relations and society development at the European Society for Therapeutic Radiology and Oncology (ESTRO), she witnesses and helps drive the “rapprochement” between radiation oncology professionals from both sides of the former iron curtain. Thanks to substantial support from target tailored EU projects, ESTRO was in a position to give a powerful impulse to the re-integration of Central European RT in the mainstream of European health care. The author describes from her own and privileged perspective the excitement of discovering the rich heritage of a shared common past and expresses her concern that in the dynamic repositioning of Europe's point of gravity towards the East, the multiple but still fragile links between Central- and West European radiotherapy, tied within ESTRO, should not get dissolved in transition.

Grid-based Visualization Framework  

NASA Astrophysics Data System (ADS)

Advances in science and engineering have put high demands on tools for high-performance large-scale visual data exploration and analysis. For example, earthquake scientists can now study earthquake phenomena from first principle physics-based simulations. These simulations can generate large amounts of data, possibly high spatial resolution, and long time series. Single-system visualization software running on commodity machines cannot scale up to the large amounts of data generated by these simulations. To address this problem, we propose a flexible and extensible Grid-based visualization framework for time-critical, interactively controlled visual browsing of spatially and temporally large datasets in a Grid environment. Our framework leverages Grid resources for scalable computation and data storage to maintain performance and interactivity with large visualization jobs. Our framework utilizes Globus Toolkit 2.4 components for security (i.e., GSI), resource allocation and management (i.e., DUROC, GRAM) and communication (i.e., Globus-IO) to couple commodity desktops with remote, scalable storage and computational resources in a Grid for interactive data exploration. There are two major components in this framework---Grid Data Transport (GDT) and the Grid Visualization Utility (GVU). GDT provides libraries for performing parallel data filtering and parallel data exchange among Grid resources. GDT allows arbitrary data filtering to be integrated into the system. It also facilitates multi-tiered pipeline topology construction of compute resources and displays. In addition to scientific visualization applications, GDT can be used to support other applications that require parallel processing and parallel transfer of partial ordered independent files, such as file-set transfer. On top of GDT, we have developed the Grid Visualization Utility (GVU), which is designed to assist visualization dataset management, including file formatting, data transport and automatic byte swapping. GVU also supports parameterized data reduction filters such as point sampling with scalar range culling, as well as volume cropping, and down sampling. The GVU framework can be used to facilitate the parallel execution of existing transformation filters, such as the VTK marching cubes iso-surface filter, as well as other custom domain-specific filters. Our initial implementation supports remote synthesis of view point independent display lists. This feature allows the local display machine to control the view point for reduced view point latency, and multi-view rendering (e.g., stereo rendering). The poster will provide an architectural design of the Grid-based visualization framework and its components. We will also show a brief demo/movie of our work, and how it is being used to visualize 4D earthquake wave propagation data.

POWER GRID RELIABILITY AND SECURITY  

SciTech Connect

This project has led to the development of a real-time simulation platform for electric power grids called Grid Simulator or GridSim for simulating the dynamic and information network interactions of large- scale power systems. The platform consists of physical models of power system components including synchronous generators, loads and control, which are simulated using a modified commercial power simulator namely Transient Stability Analysis Tool (TSAT) [1] together with data cleanup components, as well as an emulated substation level and wide-area power analysis components. The platform also includes realistic representations of communication network middleware that can emulate the real-time information flow back and forth between substations and control centers in wide-area power systems. The platform has been validated on a realistic 6000-bus model of the western American power system. The simulator GridSim developed in this project is the first of its kind in its ability to simulate real-time response of large-scale power grids, and serves as a cost effective real-time stability and control simulation platform for power industry.

The Design of Grids in Web Surveys  

PubMed Central

Grid or matrix questions are associated with a number of problems in Web surveys. In this paper, we present results from two experiments testing the design of grid questions to reduce breakoffs, missing data, and satisficing. The first examines dynamic elements to help guide respondent through the grid, and on splitting a larger grid into component pieces. The second manipulates the visual complexity of the grid and on simplifying the grid. We find that using dynamic feedback to guide respondents through a multi-question grid helps reduce missing data. Splitting the grids into component questions further reduces missing data and motivated underreporting. The visual complexity of the grid appeared to have little effect on performance. PMID:25258472

Interactive solution-adaptive grid generation  

NASA Technical Reports Server (NTRS)

TURBO-AD is an interactive solution-adaptive grid generation program under development. The program combines an interactive algebraic grid generation technique and a solution-adaptive grid generation technique into a single interactive solution-adaptive grid generation package. The control point form uses a sparse collection of control points to algebraically generate a field grid. This technique provides local grid control capability and is well suited to interactive work due to its speed and efficiency. A mapping from the physical domain to a parametric domain was used to improve difficulties that had been encountered near outwardly concave boundaries in the control point technique. Therefore, all grid modifications are performed on a unit square in the parametric domain, and the new adapted grid in the parametric domain is then mapped back to the physical domain. The grid adaptation is achieved by first adapting the control points to a numerical solution in the parametric domain using control sources obtained from flow properties. Then a new modified grid is generated from the adapted control net. This solution-adaptive grid generation process is efficient because the number of control points is much less than the number of grid points and the generation of a new grid from the adapted control net is an efficient algebraic process. TURBO-AD provides the user with both local and global grid controls.

Undesirable distortions of electrical grid conductors (12) from thermal cycling are minimized and related problems such as unwanted thermionic emission and structural failure from overheating are avoided by providing for a flow of fluid coolant within each conductor (12). The conductors (12) are secured at each end to separate flexible support elements (16) which accommodate to individual longitudinal expansion and contraction of each conductor (12) while resisting lateral displacements, the coolant flow preferably being directed into and out of each conductor through passages (48) in the flexible support elements (16).

Grid for Earth Science Applications  

NASA Astrophysics Data System (ADS)

The civil society at large has addressed to the Earth Science community many strong requirements related in particular to natural and industrial risks, climate changes, new energies. The main critical point is that on one hand the civil society and all public ask for certainties i.e. precise values with small error range as it concerns prediction at short, medium and long term in all domains; on the other hand Science can mainly answer only in terms of probability of occurrence. To improve the answer or/and decrease the uncertainties, (1) new observational networks have been deployed in order to have a better geographical coverage and more accurate measurements have been carried out in key locations and aboard satellites. Following the OECD recommendations on the openness of research and public sector data, more and more data are available for Academic organisation and SMEs; (2) New algorithms and methodologies have been developed to face the huge data processing and assimilation into simulations using new technologies and compute resources. Finally, our total knowledge about the complex Earth system is contained in models and measurements, how we put them together has to be managed cleverly. The technical challenge is to put together databases and computing resources to answer the ES challenges. However all the applications are very intensive computing. Different compute solutions are available and depend on the characteristics of the applications. One of them is Grid especially efficient for independent or embarrassingly parallel jobs related to statistical and parametric studies. Numerous applications in atmospheric chemistry, meteorology, seismology, hydrology, pollution, climate and biodiversity have been deployed successfully on Grid. In order to fulfill requirements of risk management, several prototype applications have been deployed using OGC (Open geospatial Consortium) components with Grid middleware. The Grid has permitted via a huge number of runs to decrease uncertainties by increasing the probability of occurrence and to create large database devoted for future satellite instrument. Some limitations are related to the combination of databases-outside the grid infrastructure like ESGF (Earth System Grid Federation) and grid compute resources; and to real-time applications that need resource reservation in order to insure results at given time. However some solutions have been developed. The major lesson we learnt with Grid is the impact of e-collaboration among various scientific technical domains on the development of ES research in Europe.

Convectively cooled electrical grid structure  

DOEpatents

Undesirable distortions of electrical grid conductors from thermal cycling are minimized and related problems such as unwanted thermionic emission and structural failure from overheating are avoided by providing for a flow of fluid coolant within each conductor. The conductors are secured at each end to separate flexible support elements which accommodate to individual longitudinal expansion and contraction of each conductor while resisting lateral displacements, the coolant flow preferably being directed into and out of each conductor through passages in the flexible support elements. The grid may have a modular or divided construction which facilitates manufacture and repairs.

Scientific Computing on the Grid  

SciTech Connect

Computer simulations are becoming increasingly important as the only means for studying and interpreting the complex processes of nature. Yet the scope and accuracy of these simulations are severely limited by available computational power, even using today's most powerful supercomputers. As we endeavor to simulate the true complexity of nature, we will require much larger scale calculations than are possible at present. Such dynamic and large scale applications will require computational grids and grids require development of new latency tolerant algorithms, and sophisticated code frameworks like Cactus to carry out more complex and high fidelity simulations with a massive degree of parallelism.

Grid Collector: Facilitating Efficient Selective Access from DataGrids  

SciTech Connect

The Grid Collector is a system that facilitates the effective analysis and spontaneous exploration of scientific data. It combines an efficient indexing technology with a Grid file management technology to speed up common analysis jobs on high-energy physics data and to enable some previously impractical analysis jobs. To analyze a set of high-energy collision events, one typically specifies the files containing the events of interest, reads all the events in the files, and filters out unwanted ones. Since most analysis jobs filter out significant number of events, a considerable amount of time is wasted by reading the unwanted events. The Grid Collector removes this inefficiency by allowing users to specify more precisely what events are of interest and to read only the selected events. This speeds up most analysis jobs. In existing analysis frameworks, the responsibility of bringing files from tertiary storages or remote sites to local disks falls on the users. This forces most of analysis jobs to be performed at centralized computer facilities where commonly used files are kept on large shared file systems. The Grid Collector automates file management tasks and eliminates the labor-intensive manual file transfers. This makes it much easier to perform analyses that require data files on tertiary storages and remote sites. It also makes more computer resources available for analysis jobs since they are no longer bound to the centralized facilities.

Additional Security Considerations for Grid Management  

NASA Technical Reports Server (NTRS)

The use of Grid computing environments is growing in popularity. A Grid computing environment is primarily a wide area network that encompasses multiple local area networks, where some of the local area networks are managed by different organizations. A Grid computing environment also includes common interfaces for distributed computing software so that the heterogeneous set of machines that make up the Grid can be used more easily. The other key feature of a Grid is that the distributed computing software includes appropriate security technology. The focus of most Grid software is on the security involved with application execution, file transfers, and other remote computing procedures. However, there are other important security issues related to the management of a Grid and the users who use that Grid. This note discusses these additional security issues and makes several suggestions as how they can be managed.

A new look at immune privilege of the eye: dual role for the vision-related molecule retinoic acid.  

PubMed

The eye is an immunologically privileged and profoundly immunosuppressive environment. Early studies reported inhibition of T cell proliferation, IFN-? production, and generation of regulatory T cells (Tregs) by aqueous humor (AH) and identified TGF-? as a critical factor. However, T cell subsets including Foxp3(+) Treg and Th17 were unknown at that time, as was the role of retinoic acid (RA) in Treg induction. Consequently, the effect of the ocular microenvironment on T cell lineage commitment and function, and the role of RA in this process, had not been explored. We now use gene-manipulated mice and highly purified T cell populations to demonstrate that AH suppresses lineage commitment and acquisition of Th1 and Th17 effector function of naive T cells, manifested as reduction of lineage-specific transcription factors and cytokines. Instead, AH promoted its massive conversion to Foxp3(+) Tregs that expressed CD25, GITR, CTLA-4, and CD103 and were functionally suppressive. TGF-? and RA were both needed and synergized for Treg conversion by AH, with TGF-?-enhancing T cell expression of RA receptor ?. Newly converted Foxp3(+) Tregs were unstable, but were stabilized upon continued exposure to AH or by the DNA demethylating agent 5-aza-2'-deoxycytidine. In contrast, T cells already committed to effector function were resistant to the suppressive and Treg-inducing effects of AH. We conclude that RA in the eye plays a dual role: in vision and in immune privilege. Nevertheless, primed effector T cells are relatively insensitive to AH, helping to explain their ability to induce uveitis despite an inhibitory ocular microenvironment. PMID:21918194

Smart Grid Communications System Blueprint  

NASA Astrophysics Data System (ADS)

Telecommunications operators are well versed in deploying 2G and 3G wireless networks. These networks presently support the mobile business user and/or retail consumer wishing to place conventional voice calls and data connections. The electrical power industry has recently commenced transformation of its distribution networks by deploying smart monitoring and control devices throughout their networks. This evolution of the network into a `smart grid' has also motivated the need to deploy wireless technologies that bridge the communication gap between the smart devices and information technology systems. The requirements of these networks differ from traditional wireless networks that communications operators have deployed, which have thus far forced energy companies to consider deploying their own wireless networks. We present our experience in deploying wireless networks to support the smart grid and highlight the key properties of these networks. These characteristics include application awareness, support for large numbers of simultaneous cell connections, high service coverage and prioritized routing of data. We also outline our target blueprint architecture that may be useful to the industry in building wireless and fixed networks to support the smart grid. By observing our experiences, telecommunications operators and equipment manufacturers will be able to augment their current networks and products in a way that accommodates the needs of the emerging industry of smart grids and intelligent electrical networks.

Grid Logging: Best Practices Guide  

SciTech Connect

The purpose of this document is to help developers of Grid middleware and application software generate log files that will be useful to Grid administrators, users, developers and Grid middleware itself. Currently, most of the currently generated log files are only useful to the author of the program. Good logging practices are instrumental to performance analysis, problem diagnosis, and security auditing tasks such as incident tracing and damage assessment. This document does not discuss the issue of a logging API. It is assumed that a standard log API such as syslog (C), log4j (Java), or logger (Python) is being used. Other custom logging API or even printf could be used. The key point is that the logs must contain the required information in the required format. At a high level of abstraction, the best practices for Grid logging are: (1) Consistently structured, typed, log events; (2) A standard high-resolution timestamp; (3) Use of logging levels and categories to separate logs by detail and purpose; (4) Consistent use of global and local identifiers; and (5) Use of some regular, newline-delimited ASCII text format. The rest of this document describes each of these recommendations in detail.

Grid-coordinate generation program  

USGS Publications Warehouse

This program description of the grid-coordinate generation program is written for computer users who are familiar with digital aquifer models. The program computes the coordinates for a variable grid -used in the 'Pinder Model' (a finite-difference aquifer simulator), for input to the CalComp GPCP (general purpose contouring program). The program adjusts the y-value by a user-supplied constant in order to transpose the origin of the model grid from the upper left-hand corner to the lower left-hand corner of the grid. The user has the options of, (1.) choosing the boundaries of the plot; (2.) adjusting the z-values (altitudes) by a constant; (3.) deleting superfluous z-values and (4.) subtracting the simulated surfaces from each other to obtain the decline. Output of this program includes the fixed format CNTL data cards and the other data cards required for input to GPCP. The output from GPCP then is used to produce a potentiometric map or a decline map by means of the CalComp plotter.

Network mechanisms of grid cells  

PubMed Central

One of the major breakthroughs in neuroscience is the emerging understanding of how signals from the external environment are extracted and represented in the primary sensory cortices of the mammalian brain. The operational principles of the rest of the cortex, however, have essentially remained in the dark. The discovery of grid cells, and their functional organization, opens the door to some of the first insights into the workings of the association cortices, at a stage of neural processing where firing properties are shaped not primarily by the nature of incoming sensory signals but rather by internal self-organizing principles. Grid cells are place-modulated neurons whose firing locations define a periodic triangular array overlaid on the entire space available to a moving animal. The unclouded firing pattern of these cells is rare within the association cortices. In this paper, we shall review recent advances in our understanding of the mechanisms of grid-cell formation which suggest that the pattern originates by competitive network interactions, and we shall relate these ideas to new insights regarding the organization of grid cells into functionally segregated modules.

The National Grid Project: A system overview  

NASA Technical Reports Server (NTRS)

The National Grid Project (NGP) is a comprehensive numerical grid generation software system that is being developed at the National Science Foundation (NSF) Engineering Research Center (ERC) for Computational Field Simulation (CFS) at Mississippi State University (MSU). NGP is supported by a coalition of U.S. industries and federal laboratories. The objective of the NGP is to significantly decrease the amount of time it takes to generate a numerical grid for complex geometries and to increase the quality of these grids to enable computational field simulations for applications in industry. A geometric configuration can be discretized into grids (or meshes) that have two fundamental forms: structured and unstructured. Structured grids are formed by intersecting curvilinear coordinate lines and are composed of quadrilateral (2D) and hexahedral (3D) logically rectangular cells. The connectivity of a structured grid provides for trivial identification of neighboring points by incrementing coordinate indices. Unstructured grids are composed of cells of any shape (commonly triangles, quadrilaterals, tetrahedra and hexahedra), but do not have trivial identification of neighbors by incrementing an index. For unstructured grids, a set of points and an associated connectivity table is generated to define unstructured cell shapes and neighboring points. Hybrid grids are a combination of structured grids and unstructured grids. Chimera (overset) grids are intersecting or overlapping structured grids. The NGP system currently provides a user interface that integrates both 2D and 3D structured and unstructured grid generation, a solid modeling topology data management system, an internal Computer Aided Design (CAD) system based on Non-Uniform Rational B-Splines (NURBS), a journaling language, and a grid/solution visualization system.

Grid computing in image analysis.  

PubMed

Diagnostic surgical pathology or tissue–based diagnosis still remains the most reliable and specific diagnostic medical procedure. The development of whole slide scanners permits the creation of virtual slides and to work on so-called virtual microscopes. In addition to interactive work on virtual slides approaches have been reported that introduce automated virtual microscopy, which is composed of several tools focusing on quite different tasks. These include evaluation of image quality and image standardization, analysis of potential useful thresholds for object detection and identification (segmentation), dynamic segmentation procedures, adjustable magnification to optimize feature extraction, and texture analysis including image transformation and evaluation of elementary primitives. Grid technology seems to possess all features to efficiently target and control the specific tasks of image information and detection in order to obtain a detailed and accurate diagnosis. Grid technology is based upon so-called nodes that are linked together and share certain communication rules in using open standards. Their number and functionality can vary according to the needs of a specific user at a given point in time. When implementing automated virtual microscopy with Grid technology, all of the five different Grid functions have to be taken into account, namely 1) computation services, 2) data services, 3) application services, 4) information services, and 5) knowledge services. Although all mandatory tools of automated virtual microscopy can be implemented in a closed or standardized open system, Grid technology offers a new dimension to acquire, detect, classify, and distribute medical image information, and to assure quality in tissue–based diagnosis.

Lattice boltzmann method on composite grids  

PubMed

A composite block-structured lattice Boltzmann method is proposed for the simulation of two-dimensional incompressible fluid flows. The grid structure is composed of a coarse base grid and one or several fine grid(s). The former covers the entire physical domain; the latter are placed at regions where local grid refinement is desirable. The simulation is first carried out on the base grid level at a smaller relaxation time, allowing a rapid propagation of boundary information throughout the entire domain. Thus large-scale flow features can be resolved efficiently at a relatively low cost. At a later time, fine grid variables are initiated. The dependent variables on both grid levels are, then, advanced in time simultaneously with the fine grid boundary conditions obtained from the base grid solution at the grid interface. As a demonstration, the lid-driven cavity flow is selected for study. The results show good agreement with benchmark numerical data and those calculated from the finite-volume U2RANS model. The proposed method is able to produce accurate solutions on fine grids, with a considerable saving in CPU time. PMID:11088688

Thus large-scale flow features can be resolved efficiently at a relatively low cost. At a later time, fine grid variables are initiated. The dependent variables on both grid levels are, then, advanced in time simultaneously with the fine grid boundary conditions obtained from the base grid solution at the grid interface. As a demonstration, the lid-driven cavity flow is selected for study. The results show good agreement with benchmark numerical data and those calculated from the finite-volume U2RANS model. The proposed method is able to produce accurate solutions on fine grids, with a considerable saving in CPU time.

Partitioning strategies for structured multiblock grids  

Microsoft Academic Search

A framework is presented for partitioning of multiblock grids used in data parallel applications. It includes partitioning strategies found in the literature, as well as new algorithms proposed here. In particular, a multilevel graph-partitioning strategy – specifically designed for structured composite grids – is proposed. Different partitioning strategies are compared in two case studies involving multiblock grids. One of the

Stochastic unit commitment in smart grid communications  

Microsoft Academic Search

There is growing interest in renewable energy resources and smart grid. Since most renewable sources are highly intermittent, they can induce significan fluctuation on the supply side of the power grid. On the other hand, the use of smart meters and smart appliances in the smart grid can cause significan uncertainties on the demand side as well. Unit commitment scheduling
